Should I ask if he’s sleeping with other women?

So I’ve been talking to a guy on and off since October.. we met on bumble and met for the first time in Dec... I like him and I think he likes me lol we’ve only hung out a couple times, we live an hour apart and both have kids so it’s hard to find time… But I’ve been having unprotected sex with him the last two times I saw him and he’s been finishing in me…

The thing is i know he’s at least talking to other women ( I recreated a bumble just to check and saw him active on there) but I’m worried if he’s having unprotected sex with me he’s probably doing it with other women to right ? I know it’s very stupid, and I’m going to stop but I just wanna know if there’s a way to bring it up since we’re not exclusive ... he said he was looking for a relationship but idk.. I just feel bad after having sex that he’s still on there but I guess it’s his right... I just have feelings but I don’t want to waste my time..any advice ?
