Fake it???

o you stop him and Ok so we hear a lot about ladies faking the big “O”.. my question is if you are with a guy and things are just kinda meehhhhh I mean he is trying he is fucking you but it just don’t seem to be all that good do you stop him and just drop it?? Or do you fake it and make him feel like he was good?? To be honest I have faked it.. in hopes not to make him feel badly and if I figure he might be better another time.. so what do you do??

if its not good just dont me that guy anymore

I just say that it's not a good time for me, right now and, either set-up another time to get together, or apologize and wind things down--usually by getting him off, at least.
