Help with orgasm!!!!

Gweeya • 16
I'm almost 17 and I've done everything, I'll be on top and rub my clit and my boyfriend will use his hands and I'll try by mysel. Still nothing. I have a very low sex drive and it's starting not to feel good anymore and I'm on the pill so I think that's why? I need ideas on how it can feel better and how to make me orgasm, also how do you know when you do?
