sometimes

Michellee
So me nd my bf been doing it mostly every night. Fun! 
But we don't always cum like he will but I won't.. he fingers me which is pretty good nd sometimes I do sometimes I don't .. nd then there's times when I'm not wet anymore after I was like 2 seconds ago. (makes sense?) idk what to do I feel like I fail as a gf help 
Is it me or is it him.
