I can’t orgasm...

So I’ve had sex and that feels really good and I masturbate quite a bit but for some reason I can’t orgasm. I get really close and I squirt but I just don’t know if I have/ can. Anyone got any tips??

Update:

I tried some relaxation techniques and making sure there was nobody in the house to stress about walking in on me and I orgasmed which is fab but I still didn’t happen that often. I then came home drunk one time and I have a very open and friendly relationship with my parents (eg I told them I was gonna have sex and should I go on the pill ect) and I asked my mum if I could get a vibrator as I’m too young to buy one for myself and if I did get one online then they’d know when it arrived. So about 2 weeks later when I was sober she brought it up again and said if I still wanted one she’d buy it for me and honestly that vibrator has helped me so much. A few nights ago I orgasmed 3 times in a row and it was incredible!!!
