Kinda bi, need advice

Right so I really want to have sex with men. Never tried it, really want to. But I freak out every time I get close to inviting someone over on grindr. I’m 18, can’t come out as bi or anything because people around here wouldn’t let me live with it (small town). So I can’t meet someone and hook up with them, grindr and other social media stuff seems to be my only option, so does anyone have advice? Sorry for the vague question but I really want to this before college in 6 months
