I need some advise please

For the past 6 months I was on birth control but I decided to stop because I was getting really terrible headaches. I communicated this to my boyfriend and we decided to go back to the pull out method. It’s been a month since I’ve been off birth control but I feel like he cums inside of me still but I’m not too sure. It feels warm and I feel super wet after that but then we continue doing it. Can you please tell me how it feels when a guy cums inside?? I don’t want to confront him until I’m positive that’s the case.
