advice?

S
so 2 nights ago I was with my friend Alex and we went and smoked weed (normal for us) with 2 guys. one of the guys she's been fw for a while and the other guy I've flirted with a little bit. so we were all really high and the other 2 went in a room and me and this guy are together and we're making out whatever nothing new. but then it got so intense, like he was sucking on my neck and my nipples and going down my stomach and oh my man😻😻he's the first guy that has ever seen me without a shirt on and that actually made me feel comfortable. I would've done more if it wasn't for my mf period🙄but I'm 16 and I'm a virgin. the farthest I've gone with a guy is making out. I know I want to wait until 18 to have sex but I feel awful now after doing all that. like I enjoyed it so so much but we aren't serious. I know before I do anything sexual fr I want to be in a relationship with the guy but no guys are actually serious. but I also want to do more with him again. so idk I'm confused asf. should I feel ashamed for that?
