I want more sex. But often get rejected cuz she's tired or "doesn't feel like it", and sometimes cuz she's on her period. In these cases, she would stop me when I start making out with her.

I'm already increasing my SMV everyday by lifting. What's wrong, why is she rejecting sex from me, and what should I do to fix it?

The fact that she still works in my favor (logistically she cancels plans to meet me, travels all the way, and pays for meals)... So I'm not sure why a girl would be doing this BUT NOT HAVING SEX WITH ME. I may be overthinking this, perhaps she just has a low libido.

Any help would be good!
