it may not be exactly what u want since they don't show 'it' but the MCs didn't know that they were gay so it works out ^^ and there's more, this one's the first in the series, personally I read http://www.mangago.zone/read-manga/hanaya_no_nikai_de/ first (ironically its the last one I know of) and its still my favorite, they r in order in my yaoi list so here if u r interested.

This is it, thank you!
Thank you. I've not read this one but I will. Thanks.
^^ Welcome ^^
I might be about to mix my Manga's.
I would like to find a Yaoi about a guy who goes to the same club a lot.
A straight guy falls for him and then there's a bit when it seems like they are going to do it but the straight guy sees his penis and makes a run for it.
Later they get together and the straight guy comes up with some stupid reason like 'I was so turned on I had to leave' or something like that.
Does anyone know it?
