Short answer, NO. Not all gay men are into the same activities.. I am quite partial to anal intercourse and giving oral to a guy, is always a secondary activity, and or foreplay to me. Now, this isn't to say I would not give a whole night of oral to a guy who really enjoyed oral.. In other words, If I hooked up with a guy, and I knew his biggest joy came from getting oral sex.. I would do my best job at oral for him.. I However, am not as keen on giving it to a guy as I am anal, and its a matter of personal interest.
Not all guys are into the same activities.. there are other threads where some guys on this website get all uppity, about Oral intercourse in an almost elitist Jerk kind of way. . I have (Anal-Pride), as a bottom.. and for all the other guys out there like me, (you are not alone). Don't let the Oral Fascist-gays box you into a corner. We have a right to enjoy our activities too.
Anyway,. . recap.. NO.. Not all guys enjoy giving oral.. Just like not all guys are into Anal activities.
