I haven't had sex a lot, i don't know how normal this is or not. But yeah so far every time I've had a guy penetrate me, by the end I feel so drained and I have a hard time not falling asleep. And this is kind of embarrassing but admittedly I don't even do much once the guy is in me. I just take him and he does most of the work. Which is lame I know but the point is I don't know why it drains me so much if I'm not doing much.
Why is that happening, is it normal? How can I avoid being that exhausted? thank you
