Sex question


I’ve hooked up with this guy a few times now but it’s definitely just sex.

The two last times we’ve hooked up at the end he takes the condom off, puts it in two or three times, and then pulls out and will finish on me or in my mouth.

Is this a normal thing guys do??

Whats the point of using protection if you’re gonna take it off lmao?

I know he’s clean, but should I be concerned about precum? Also how do I have a talk with him cause I don’t think I’m comfortable with that (I’m not on any other form of birth control). Should I be concerned? Have y’all ever had a guy do this?
