I don’t think he’s very good at pulling out

So I just recently started having sex with a friend. We don’t use condoms and he’s relying heavily on the pull out method. So we’ve done it a few times and I noticed that when he pulls out there’s already cum on his opening and I feel very wet. It could be my imagination or I’m over reacting. Pre cum maybe. I don’t know if I should stop having sex with him. The pill and the IUD is not an option and I’m lost at how to introduce condoms.
