What does Endo pain feel like like? THIS I know alllll (way too much) about!
I could be sitting perfectly still. Without moving, all of a sudden it feels like barbed wire has "appeared" around my girly organs. If, at that point, I do move (which is impossible not to do), it feels like someone is tugging on that barbed wire.
During sex, there *might* be some discomfort, but it pales in comparison.

However, AFTER sex, the pain has put me in tears and sometimes I have to get into the fetal position and stay put for like 15 minutes. It's so unfair lol...amazing sex and then paralyzing pain. Hubby feels bad so sometimes I have to really convince him that I think it's worth it. Plus we are trying to conceive.
This pain after sex is usually the worst right before my period or if I'm late for my period. Another thing is I know that my period is coming because about two days beforehand, I will feel like my lower back has nails hammered in. I can't stand straight, can't sit comfortably...the most comfortable I am is when I'm flat on my back on a hard surface, and even then it still hurts.
Here's the big one...and if you don't have it, it doesn't mean you don't have Endo...it just means you're lucky enough to not get this kind of pain. RECTAL PAIN. OMG this is the worst. I get these sharp, stabbing, acute pains...sometimes if I'm going #2 and sometimes just because. It's enough to make me jump a little bit and my whole body stiffens. It's really bad, strange, weird, aggravating.
I tried to have lap surgery for it back on November. My OB/GYN said it failed because of my weight. (I call BS - I know women larger than myself who have had it successfully and they use lap for gastric bypass! I think he was just lazy and my weight was the most convenient excuse). I'm going to give it a 2nd try with a really really good doctor. I have my consultation appointment on Thursday.
Good luck with your surgery!!!
