Hair down there

So I’m almost 15 and I’ve been shaving down there since I was like 12 years old. But when I shave it sometimes leaves razor bumps/ ingrown hair. And usually it wouldn’t bother me as much but now I’m having my first serious boyfriend, and sometimes I think we might do something. And I want it to be nice down there. And I can’t really ask my dad because I’m not allowed to date so I have to sneak over his house, ( his mom is there don’t worry ) and plus it would be weird to ask my dad. So is there anything I could do to not have that happen?
