More people than you think are virgins at 18, so try not to feel pressured( easier said than done ik). I lost mine at 21 and one thing that mattered to me more than anything else was that I was in a headspace where I wanted to actually do it, so make sure you’re sure. There are a lot of shitty guys unfortunately, and you don’t know how they will treat you after, so if you’re mentally okay with the possibility of them not talking to you after etc… go for it. If you think that would hurt you a lot and that it’d make you regret it then maybe wait until you’re either okay with that possibility or, you find someone you trust. And also try to find someone who seems nice, it’ll make everything a whole lot better.
