<human>: We met on OK Cupid, neither of us wanted a relationship, but we had the best sex, and amazing chemistry. I ended up developing feelings for him so we agreed to be just friends and we hang out every now and then. It's all very casual and we treat each other as platonic friends. He'll probably never want a monogamous relationship, and I've been pretty burned from previous relationships and can't stand the thought of falling for someone again. 

While being friends, we found out one of us gave each other herpes, we can't be sure which one had it first. 

We've both been dating other people but I've not slept with anyone since finding out about the herpes. Thing is I'm a very sexual person and also, I've been having lots of sexual thoughts and dreams about my ex FWB. Is it just too selfish to ask him if he'd want to resume the sexual aspect of our relationship again?

What would you do/think if you were in his position?

Could you distill the essence of the text into 1-3 sentences?
<bot>: I want to bring up the possibility of bringing back benefits with my former FWB though I'm the one who took them away in the first place.
