I’m straight, but dicks are objectively more aesthetic than vaginas.
Now let me establish clearly that I am as heterosexual as it gets. Nothing against gay folks I’m just not one. HOWEVER. Penises *look* so much better in just about every way. Vaginas look gross. I’m still able to fuck my girlfriend because I don’t have to think about it and it just feels good. When it comes to cunnilingus though… the only way to power through it is to imagine I’m sucking a nice juicy cock. Seriously. And it’s not her fault; there’s nothing wrong with her, it’s just always been like this. So yea, penises are a much more pleasing sexual organ to look at it and (presumably) experience. Straight girls are lucky.
