How do I know if I came

Last two days I’ve had sex with a guy and he would ask me if I came & I would be like tbh I’m not sure . Cause I can’t tell if I did or not & he would just say I think you did bc your really wet . I asked my friend and she was like if your wet , you came . Like I get wet bc I’m turned on but like during sex it’ll get more wet.

How do I know if I came ? Like clearly I can see him cum bc he literally pulls out just to cum but idk about me and he says he’s gonna make me come but how will I know if I did lmao , I think he’s gonna be focused on making me come and not making me comfortable & feeling good .
