I always masturbate myself after my bfs cum..

ok im wondering if it's just me, but since I started dating my bf we have sex almost every day, he always cum, but the first year i never cum ( honestly I don't know the difference between cum and orgasm ) but I felt pleasure all the time, there was a time that I left him for months cause relationship problems, I started dating a girl , it was my first time having sex with a girl so she made me cum I knew it was that cause i was feeling amazing and I couldn't control it i even squirt first time obviously lol I thought it was pee😭😭😂 so hilarious I pushed her face anyways after a while i got back w my man and normally I don't cum unless he's licking my boobs or playing w my pussy  but I don't cum by him just putting his dick on me , i had to get my tities rub or my click , so he always cum and I barely by having just sex w nothing extra so after he cum I just watch lesbians porn and then i play w myself and i cum😭😭 im sorry for being so described, tnks God I don't have to see ur faces 🙄 so shy, but anyways , is that normal?
