Filss, you must be a transplant to Toulousse and not a native as many of the French str8 guys I know seem "obsessed" with sex (as compared to us Americans) and are very comfortable talking about and looking at others guy's penises.
Tell me, the last time you went to the beach in France, didn't you see naked guys and girls of all age types and LOOK at the women? (I say that since you profile says you're Gay) And in looking at these women, I'm sure admired some of the nicer breasts or toned bodies. This in iteself is your admiration of the sex WITHOUT sexual attraction.
YES, it is possible some of the guys on here hide behind the screen of their str8 profile BUT equally so, you can be sure there are many str8 guys on here that ARE big, WANT to be big, or are just BIG curious and admire the COCK but are not GAY.
Don't get stuck on labels.
