Oh my heavens, a nakie pic right outta the gate -- yeah, that's class! So sorry you've had these jerks accost you in this way, WG. And yeah, pressing the SEX buttons almost immediately IS A JERK MOVE. I am furious on your behalf!
I've not done internet dating, but I've met some guys on social media who decided I should be thrilled w/their inappropriate attentions. It was scarey and it pissed me off, especially since I had e-known the one guy (and had met him IRL some time earlier) for 4 or 5 years and always thought he was a good guy -- smart, funny, respectful, observant, interesting, all the good stuff. Yeah, no. All it took was for me to suddenly be single and BOOM. Ugly happened.
It actually hurt my feelings, so I told one of my friends about it and he was all:"Omg, dating sites are worse: You have to put right away that you want someone who shares your values. and aren't looking for a hook-up -- and even then it's a minefield!" And he's MALE! I about fainted.

I cannot for the life of me understand why and how people feel it appropriate to behave in a fashion on the internet, which they would never ever in a zillion years consider doing IRL. It infuriates the sox off me: C'mon, would you walk up to someone on the street and drop trou, expecting them to be delighted at the sight of your bare bits??? REALLY??!!

GAH.

Sorry, I'm no help. It's just crazymaking that people believe they don't need to proceed with consideration and respect when pursuing a new friendship/relationship,, regardless of the medium they're using. It's dehumanizing, imo.

Rant over.

Best,
