ingrown hair? smell? shaving?

Okay so I've come on here for some serious help. I don't really have any females around me that can help me out. So I've been getting a lot of ingrown hairs on my vagina and they hurt. Any way I can make them go away? And what kind of electric shaver/trimmer would be best? I'm done using the razor and I've heard that the trimmer would be best. ALSO, what can I do about a smell down there? I've noticed it smells a bit tbh. Not like a very bad odor but it's noticeable by me. When I shower I use water and a little bit of soap to wash down there. I don't put soap near the opening or anything. The smell usually doesn't come until like after I've had discharge or sex. Usually after sex I wipe it. But would it be best to shower after or use some wet wipes? I don't know.
