I'm turning 21 in a couple of months. I've never been in a relationship but recently I've been looking for one. I am still a virgin and I have been wanting to have sex more and more often lately. So recently I bought condoms for the first time. I have been on dating apps before but I haven't really committed to meeting new people. This year I have meet this guy on a dating app called Happn. When I met him he was really nice but he told me that he wants to be friends with benefits. I said ok but i also told him that I am a virgin and that you have to take it slow. So the first day I met him we watched a Netflix movie and he asked me if he can smoke pot and I stupidly said yes. I had no clue that pot smells so strong and that day all we did was make out but I had to leave. It smelled so bad in his apartment and when we were kissing I could taste it. It was so a turn off for me and I left and drove home and felt like I was going to throw up because of the smell. We do still text each other but that's it. I do want to fuck this guy so badly but I am afraid of getting emotionally attached. 
What do you think I should do? Should I go for it and have sex or wait until I start dating someone? Do you think my body trying to tell me that I'm ready to have sex or am I just really horny as fuck and want some dick?
