<human>: Hi reddit, I'm having trouble keeping up with my girlfriend's sex drive.  I've never been with a woman who constantly needed to have sex multiple times a day, every single day.  It gets so bad that my balls are in constant pain and I have to go slower or it hurts, but she moans that I'm not going hard enough.  I've tried using sex toys, however she seems to think that my cock is more satisfying.  

I've always been the one in my part relationships to want sex most, but not as much as this girl.  My sleep is suffering as well because she keeps waking me up 2 or 3 in the morning and then I have trouble falling back to sleep.  I love this girl and would do anything for her, but I'm afraid that if I tell her no she might try and find sex elsewhere.

Is this a big enough problem or should I just deal with it?

<bot>: gf wants sex all the time and I feel like I need breaks.  Afraid she might cheat if I refuse.
