Yes. How does having a dookie fetish and sucking dikk NOT make you less of a man? In 2015 or whenever.
Let's say you're a military cat. Hardcore military cat. You're a trained killer, and could easily yoke me or you or any of us who aren't trained. You've fought, bled, shot at and been shot at. You'd be less of a man because of your sexual preference? Or not even that stereotypical view of manhood, but just the simple things of being a man: handling your business. Taking care of your kid(s), paying your bills, holding down your significant other, and taking care of your shyt when you need to take care of your shyt and you're gay. Is he less of a man than the heterosexual deadbeat dad or the heterosexual child abuser or woman beater? Or is he less of a man that the guy who doesn't handle his business and sits on his ass all day?
Or if you've got two guys with everything being equal, one's sexual orientation is really going to make you less of a man? Again, if that's how you feel breh, cool, but I don't.
