So there's this guy that I've been talking to I met him on Fourth of July and we started texting and getting to know each other but never got the chance to meet up again but I really like talking to him or started getting little feelings. Well I ended up going to see him a couple days ago and we were hanging out i met his brother a couple friends & his ex then they all left and we made out for like two hours and I haven't done that since like high school well anyways we were making out and he kept complimenting me and he wanted to cuddle but I just kept teasing him and we ended up having sex and I stayed the night and I set an alarm for me to wake up and leave and when it went off I turned it off and I told him I needed to go and he just started pecking me and kissing me sweetly on my shoulder and my neck and cheek and just wrapped himself around me and tried to go back to sleep and I got up and was like no I have to go home and he stayed up with me for another like 30 minutes and kept kissing me his mom even came into the kitchen where we were & saw us holding each other but he didnt care. Then I went home and I feel like I could've ruined what I wanted to have with him because we had sex😕 idk how to have a relationship or start one with someone because ive never had one. I feel like i ruined those chances. Idk what to do
