Lost my virginity

Well I lost my virginity tonight about an hour ago I guess. It’s like 3 in the morning now and honestly I kind of regret it.... so I lost it to (we’ll call him A) but I’m dating (we’ll call him L). I feel like I shouldn’t feel super bad bc we went on a break earlier today. I’m fucked up for doing this at all it’s just I was upset from the whole break conversation with L and just went to drink with A and it just kind of happened :/ I feel like that shouldn’t have happened though..... we used a condom and I’m not on birth control and I’m at high risk of pregnancy. The condom didn’t break so I’m not toooo worried about being pregnant bc we used it right I just hope there wasn’t any holes or else I’m actually dead from my parents and my boyfriend.

I only sort of regret it because I’m still technically with L but I talked to A before me and L started dating.

I don’t want to tell L bc it’s just going to mess everything up...he already doesn’t trust me about anything.

By the way I’m 16 L is 17 and A is 18 I’m pretty sure

Advice?
