Im 32 weeks and some change pregnant.

Before we concieved we where extremely sexually active. Unfortunantley since being pregnant its not that my sex drive has lowered. I am just so uncomfortable when we have sex now. I cant tell if what hurts and what feels good. Not to mention TMI i always feel like im gonna pee or poop or something and when our son moves it just makes me uncomfortable because he cant feel it but i can and i feel invaded and i know my son cant feel it but he always moves more. My point is Its just extremely hard for me to enjoy sex right now. I walked downstairs a bit ago and found my husband masturbating.. and idk if its hormones but im just really upset over it. Like, i want to have sex to. But i also want to enjoy it. Idk thoughts? Comment?
