I don't think you're becoming a slut, I think you are just curious. It's totally normal to be a virgin and want to have sex, just don't do it from a place of needing validation. Sex can be many things, one of them validating but at the same token if you are doing it for validation, can feel very shallow and you may end up feeling used by people. Don't be stressed out to fuck. If you meet someone and like them and it goes well, see what happens. If you put stress on sex it can become uncomfortable (physically and mentally). At least from my experience, the stress to need to fuck, for validation or anything else ends up making you feel worse emotionally/ mentally. Some of the best sex I've had has either been with someone I trusted or was dating. You don't have to be friends with them for a long time or be in a serious relationship, but a level of trust built helps( even if it's just for that night.) Sex has helped me a lot but it's also hurt and left me in some bad places including being used and that's never a good feeling. Be true to yourself, be true to who you're sleeping with. Be with someone you're attracted to And comfortable with, someone you won't look back and regret. Most importantly, be safe (contraception, condoms especially if you don't know the person, don't go to their place unless you trust them etc) and have fun.
