Can you cum???

Little bit of an awkward question do you know when you cum?? I swear I never have or something. Would I know? I have an extremely high sex drive and no problem getting wet but can't seem to ever cum.....this is years this has been going on. Since I've started having sex at all. I'll admit it I'm very sexually experienced so I'm confused as to why I'm even having a problem with this. Help!
