No it’s not a bad thing.
The appearance of your genitals has nothing to do with your interests, hobbies or personality.

Anyone who talks about some random persons penis is a creep, even if it’s as a joke. Reverse the genders and you’ll see how it’s so fucking creepy and gross. “Haha i bet her pussy loose” “I bet her pussy lips hang out of her panties” as a reasoning behind a behavior or hobby is fucking creepy.

The “jokes” really aren’t funny anymore and it’s becoming a real issue I think. It’s just making men feel bad about them selves, and a way for people to be straight up assholes and cover it up with “i was joking bro”.
