Patch and Condoms.

My bf and I just started having sex in April and we have used a condom every single time as well as me being on bc. I don’t want to get pregnant and that is why we double up. He says he would like to cum in me with the condom on but I’m not comfortable with that yet and it also makes me kinda nervous. Am I dumb for that? Should I let him cum in me with a condom? He doesn’t pressure me or anything, it was just a question he had and he respected my answer.

Will I be ok if I let him cum?

Thank you!
