Sticking an appendage into a body is not the same thing as having someone inside you. Whenever the sexual double standard comes up inevitably some comments come up saying "if a girl's worse off for having sex then the guy is too cause they did the same thing." They did not.

In heterosexual sexual encounters, women are much more likely to catch every STD than men are except for HPV, which is 3.5% likelihood to 4%. The exception is gay men, who get penetrated, because of all the anal tearing.

Let's say you met a girl and she told you she'd been with 150 men. You form an opinion on her, be it good for her for exploring herself you go girl, she's a complete slag get away from me or anything in between.

Would your opinion not change if you discovered that she's never had PIV sex with these men in fact she convinces straight men when they're alone with her to let her peg them in the asshole.

Personally I'd move from good for you I'd never date you though, to teach me your ways senpai, this B is clearly skilled.

Similarly a guy who slept with 100s of gorgeous women but never even saw their vaginas and instead got pegged by all of them as they fondled his balls or whatever would have me drastically change my opinion on him real quick.

No one's (I'm sure someone has but not that I've heard of) experienced pain penetrating someone, but the opposite is true in plenty of cases.

Are they really the same thing in your mind, or do you just think that they should be?
