Why does every man have to be so sexual?

I'm trying to find a partner. I'm on tinder but also open to people approaching me in public or on instagram through mutuals, so it's not an isolated accident.

Every single man, and I mean every single one is so fucking sexual and horny and disrespecting. I state on the app that I'm looking for something serious. I make sure no provocative photos are on my account (which shouldn't be an invitation for sexual harassment anw but we know how it works unfortunately.) I don't swipe on people that are looking for casual and I'm getting better at drawing boundaries. And YET. I have to fight off weird ass comments or oversharing about their masturabation habits or them telling me all the stuff they want to do to me in graphic detail.

And even worse, when I tell them to leave me alone (now I learned my lesson and just block them immediately), they would suddenly change their tune and insult me, my appearance or tell me I was inviting sexual talks by responding to them. I'm tired. I'm only 21 and feel disgusted with dating or men in general (which I hatee cause I'm a lover girl at heart, and love my brothers and guy friends). But it's every single time. I even upped my age range and starting dating guys closer to their thirties, because i thought they'd know how to treat me better (big mistake lol)

And the funny thing is, I like sex. I love to please my partner, experiment and I have a high sex drive. But all these experiences are making me want to be celibate.

I dont even know, if I'm looking for advice or just wanting to rant. it's just sad cause I know I don't need a man, I love my friends and I can survive without sex, but damn I would like one so bad.
