I’m 18, just never got around to having sex cause I don’t trust people to keep things private but I am in a serious relationship rn and I want to take the next step.

I do masturbate a lot (🤣) and have for a long ass time but the only way I’ve ever been able to orgasm is with clit stimulation. I’ve never bought toys or anything but whenever I’ve tried fingering my self, I don’t feel anything and give up & go back to my clit. I’m honestly terrified that when I have sex that I won’t orgasm and have to fake it. I want to try to orgasm vaginally but it never works. :(( any advice for techniques or anything? I’ve tried everything and just can’t orgasm that way.
