If you're a bottom, don't use grindr for your virginity lol. Use bumble or hinge.
Grindr dudes are straight up predators (at least in my area). Most of them start off quite nice until you get to actually fucking. Then its basically just rape and whatever they want to do to you until they let you leave really. Happened to me a few times.
Hinge or bumble just meet someone close to your age or experience and then explore each other. Much nicer of an intro into it.
