hiii I’ve always wanted to have a threesome with 2 guys at the same time. It’s probably my longest fantasy, but I haven’t made it a reality yet. I’m curious for the guys who have done it, did you pay much attention to the size of the other guy’s dick? Were you intimidated? Did it turn you on? Just wondering how big of a factor that is for guys in a threesome. Thanks!
 
I did one with a buddy and his girlfriend in my late 20s, they were high school sweethearts in a rut and spicing things up, he wanted FMF, she countered/bluffed with only if she got a MFM and he went for it.

Although his size was the last thing on my mind, once things got going it was obvious i was much larger, i'm a thick 7 inches, he was maybe 5 on a good day and thin/average. I knew them well enough to know that she'd only been with one guy prior, seeing and hearing her reaction when i started to fuck her was a HUGE turn on knowing i was the bigger one, i'd say there was a bit of a dominance thing going on with how hard i fucked her in front of him

I haven't done a threesome with two woman but I'm pretty sure I wouldn't be interested if they have rack disparity and how they feel about it.
Perhaps i would ask more about logistics, positions, potential risks, don't try this it's just for the camera, each with one hole or collaborative?
I could care less about other men penises I would focus on the woman.

I've only had threesomes with a bud of mine and it was mostly a tag team kind of thing but we did dp too which was odd for us feeling each other thrust but we were so in the moment. The women we did it with I could tell noticed our size difference but it wasnt an issue. My bud and I had already seen each others dicks and his is 6" which is a good size anyway.

I came close to having a MFM thresome with a FWB many years ago. Since my FWB and I talked openly about sex, and she was was seeing (fucking) another guy, she brought up his size at some point when we we having sex. She said he was a little bit longer, but thinner. I'm 7 inches by 6 inches, so I'm guessing he was 7.5-8 inches long, and likely about 5 inches in girth. We didn't actually go through with the thressome as we were outside in a secluded area, hadn't planned it, and we had no condoms.

Had we gone through with it would either of our sizes mattered to each other? I doubt it. We each had fucked her dozens to hundreds of times on our own, so we knew what she liked, how she liked it, and she knew exactly what she liked and wanted from each of us.

Would it had made any difference if he was 'just average to smaller than average in size? I don't know, as that would be on him.

If he had been the super rare longer and thicker guy than me would it have impacted me? I don't think so, as again, I'd been with her so many times I'd just be concentrating on fucking her, or being on the receiving end of her great oral skills.

With the vast majority of men being in the average size range (duh!) the odds are your two partners would have much of a size disparity. Unless of course you already have the guys in mind and know there is a significant size difference?
 
It mattered to me that I was the biggest, as most of my MFM threesomes involved my wife. And I always was.
Except for this one time when she was sucking dick at a glory hole, while I fucked her doggy style. This guy was so unfeasibly big, there was no way she wanted him to fuck her.

The ones I've been part in I was the thickest as requested by the wife/gf of the other male.

I don’t think that it is a bigger factor for guys, the biggest factor is that they don’t get scared and back out. Or get totally jealous.

If it turns out into a competition of which dude can fuck you better, you would be in for a long fun night
 
Only did MFM one time. Was with a friend of mine and a chick we met at a casino. I was bigger. There was some awkwardness for a bit afterwards. Most of the awkwardness was related to the situation itself, but some of it was related to dick size. I could tell he was a bit embarrassed about it. But it just took some time and some bad jokes and we're all better now.
 
Yes, it would.

MFM is my biggest turn-on (after watching two women together).

I would have to be bigger than the other dude, by a little bit. If we were the same size, or close to it, it might cause some friction, but maybe a big turn-on somehow. Otherwise, if he's apparently bigger than me, I think jealously would ruin it for me (very, very few dudes would be bigger than me, especially in girth).

I wouldn't do an MFM with a dude who isn't hung, though, as I would get bored. I'd prefer the dude had a sexy ass, because I like to see a dude's ass when he's drilling pussy. The sexier the male ass, the more stimulating.

But in the end, it's mainly about dick size for me, with dude. I've had this fetish all of my life.

Would I interact with the dude sexually? Probably little contact. I might slap his ass when's drillin' pussy (if he's comfortable/on joking terms, etc). That would be a big turn-on, or grip his balls and laugh when he's inside her tight pussy. But that's it. I am not into sucking each other's dicks, ass sex (nor with women), etc.

^That's why I'm 20% gay, and not scared to admit it. If there is no woman with me, my 20% goes in hiding.

The woman must have big titties! I don't like shaven pussy, either.
 
I don't think it matters much, but I've always been the bigger guy, with a few exceptions regarding length. My focus has always been on the female... How many times can I make her orgasm.... How loud can I make her scream... I would imagine if there was a huge disparity between the two, the smaller guy might be intimidated...
 
I would be terribly jealous of a man who was bigger than me.

If there is no interest in the other dude at all, what’s the point of a MFM?

if all porn is all about the women for straight men, then just watch lesbian porn. Lol

I go in phases where I watch too much leabian porn. lol
 
Honestly all my buddy and I have cared about in my last few MFM's is making sure she's screaming and having nonstop orgasms

Though to be fair I'm usually on top here
You are a stud, making a woman scream like that.

I’d like to jokingly pull on your nutsack as you ram her hard in that tigjht pussy.

I'm roughly the size of your buddy and this has happened to me too. Fortunately not with a girlfriend, but with my big in the frat and some random chick. It was supposed to be a bonding thing, but my big saw how much louder and wilder she got when he was fucking her, it seemed like he was kind of into it. I still participated, she blew me and I jacked off, but he fucked her most of the time. He wasn't a dick about it, I wouldn't say I was "cucked," but it was definitely like a big bro/little bro vibe. Which is kinda what our relationship still is.

For me, it was watching my wife being sexual.

It's one thing for a wife/gf to be sexual with her partner - I mean, that's kinda expected. But watching her with another shows that she is sexual on a higher level.

Also, you get to see her from an entirely different angle/perspective.
