Just my two cents here..maybe three cents. For my own path and what I've done, and what I will continue to do, it's a gamble for me. Maybe for others if they just don't realize it at first.
First cent is, I like it a lot..i really do. of course, I have no expectations on a good BJ, or getting any kind of recip. For me, its a massive plus as they groan/moan a lot, cum fast(love that), and those legs shake/tremble when licking, nibbling, feeling and tasting them up. Another major plus is, their buttholes are extra tight and just a slit, and its so good eating them out and showing them how good anal can be when going slow. The way they open up and more is just damn good fun. Last thing is, some surprise when by trying to bttm or suck me since I have a smaller cock.
Second is, the gamble that the guy could end up very clingy or "bonding" deep over the fun. Now, that isn't only for younger guys who are inexperienced and/or curious. I've had guys in their 20's and 30's, hell, even 40's, be the same way. That they receive slow/good sex and they think they caught feelings or after a few meetups, they think they are "in love". That's always been a rough situation to break, yet, i realized, there almost is no legit reason to address it negatively. Just talking upfront, stern and with conviction/thought helps a lot.
My third cent is..if I ever find or get with a guy and he's very sexually inexperienced and I legit want to be with him, i will attempt to focus on the positives. Meaning, sure, he doesn't know what's up or what he's doing, yet, that can't outweight the fact that I can make it fun and make it a damn good memory that gets us rock hard when we think of it time later, or make newer versions of it. That might solidify our bond deeper and higher trust too.
So yea..just my few cents
