Had sex with my 30 year old boyfriend BUT!!!

I’m not a virgin but my bf was a virgin up until a few days ago

He can’t stay hard and when we are doing foreplay he gets super hard and stops.

Then we re start again foreplay and he doesn’t get hard like the time before, then he ultimately has to play out a fantasy where I’m gaining weight for him to be hard and he self pleasures himself to get hard again..

Is he not attracted to me? Is his fantasy an addiction and that’s what only gets him turned on?

Because that bothers me…if you can’t stay hard for me and gets hard at the idea of a fantasy. I mean that’s not normal..

What do I do, I told him to stop looking at that stuff on the internet and he said well if it turns me on them I’m going to do it…

**also to add this has been an issue before sex***
