Should we keep having sex?

Me and my SO are having sex like every week. We use condoms and this might be weird but he'll pull out and cum in my mouth. just how we do it i guess🤷🏼‍♀️ anyways, i really dont want to get pregnant, im young and there's no way i want or can raise a baby.

how do i tell him im too afraid of sex because of pregnancy? the condoms never broke and again... he cums in my mfing mouth but still i just cant handle the possibility of being pregnant!
