I've found SEX, of all kinds, Fascinating, simply because it was SEX! I've had more than my "fair share" of SEX with both Guys, and Girls. And, though I LOVED playing with Girls, my personal urges led me to Enjoying GUYS even more. SO ... even though my Sexual History would be rightly described as Bi, I identify as Gay. And, during the latter half of my life, all of my "Playmates" have been Guys.
Butt, that's my own personal thing. Actually acting on your "interests" is not the same as Understanding some of your core urges, and still not being interested in physically engaging in them. In other words, I can completely appreciate being attracted to Gay Porn, while not wishing to actually Experience SEX with another Dude. And, this is in spite of my advice to explore ALL options available, simply for the acquisition of that Life Knowledge. Until you've done it, you won't Really KNOW for Sure.
Still ... Guys can, innately, understand Guys, because we're all made of the same "stuff". And, though we may not wish to actually Personally Experience what SEX with another Guy might be like, we still possess the Inner Knowledge of what that might feel like. On the other hand, Chicks just simply don't "Get" That, because they simply can not Know! It's not in their Nature! And, that's also why Guys are much better cock suckers. We KNOW what it feels like! And, we don't have to do it in order to KNOW that!
Str8 Guys, enjoying Gay Porn, is not a "Mystery" to me, nor, really, any other Guy! It all boils down to Knowing how Guys/WE are Wired!
Enjoy whatever it is YOU Enjoy! Don't worry about what you might Think others might think (because you'll probably be wrong!). And, be comfortable in simply following your own Heart!
All the more reason to ... no matter what ...
Keep smilin'!!
