Is casual sex the norm now?

I took sex off the table because I realised my emotions live in my vagina (that's how Ive interpreted my personal brand of anxious attachment). The guy I was seeing (situationshiply 6 months ago) asked if I wanted to meet up and I said I'd be keen for a chat. He didn't think I meant it and he when he realised I was serious he said he was feeling lazy and didn't want to go on a date and wished me the best. I've never heard of such, is everyone else putting out? Did I go about this the wrong way?

It also felt like he had a rotation as he was booked and busy Thursday to Saturday but could "maybe" see me on Sunday. It feels so unreal
