Great story and thanks for the edit. I like that kind of story.
I only really got asked about it once in person. It was the end of term 1 in my first year at uni and I was chatting and drinking with some of my friends in the kitchen. It was past midnight when the only ones left were myself, a petite Spanish girl and a male colleague of mine whom I met from day one and became good friends with. I don’t remember what exactly we had been chatting about but the discussion ended up touching upon the subject of penile size. The girl, Maria, jokingly asked us if we were happy with our size, as most guys seem to stress too much over it. My friend, who was significantly more drunk than I was said no one ever complained, but suggested that we both show Maria what we have and she would be the judge.
I initially felt embarrassed about it and laughed it off, but Maria put on a very serious face and told us she would very much like that. My friend looked at me, and made a comment about me being a prude or something. Must have been the alcohol or the way I had exchanged some glances with Maria that night, but I felt myself getting a hard-on. Confident in at least not having to show a full softie, I got up, closed the kitchen door and told them that I accept the challenge. Maria started biting her lip and giving us some very sexy looks as we began undoing our belts. By that time I imagine the excitement got us both rock hard as both cocks snapped up as soon as we pulled our pants down, to Maria’s astonishment.
I’m around 7” long, so not massive but a tad over average and while it’s impossible to judge sizes that quickly or from a distance when inebriated, I would say that my friend’s cock was broadly similar in size and shape. Nevertheless, Maria seemed impressed and let out a “oh fuck, not complaining at all” or something.
The whole scene lasted for maybe 5 seconds before we both pulled our pants up to avoid being caught up in what seemed like the beginning of a porno should anyone have walked in on us. We continued chatting for a tad longer and then called it a night.
I never brought the scene up with anyone and my friend and I just silently agreed to forget about it between the two of us. I had my fun with cocks before, but he was the more conservative type and clearly not interested in anything else between us.
Interestingly though, a few weeks after the fact Maria and I started a short term fling that resulted in some very enjoyable sex (and good memories). I have no idea whether that night made any difference - I like to think it wasn’t a 5 second glimpse at the hard cock of an inebriated fresher that got her in bed with me.
Edit: conscious “dropping your pants” was excluded per OP’s request. My initial answer was that I am above average and happy with it, but what ensued was the result of being challenged to have something to show for it.
