After my first lap and getting a lot removed from around my cervix, uterus and rectum I do not have the pain I once had during intercourse! My husband has noticed that he can go deeper than what he could before. There are some good threads with tips on making sex less painful/more tolerable on here.
Everyone is different and someone with stage four may not have any pain, and someone with stage one can have severe pain. It is such a bizarre disease that everyone seems to have different experiences.

There are many women with this disease who enjoy pain-free sex! Keep in mind that this forum is mostly people talking about and looking for answers for what they are having problems with and those with the same experiences offering advice, so it is unlikely to see someone talking about great, pain-free sex, does that make sense?

Don't worry or fret unless it becomes an issue for you. I have found that if you worry or fret about each potential thing that can become problematic with endo that you may see on here, you can make yourself crazy. One step at a time. Hopefully intercourse won't be painful for you, but if it is, this is the place to ask about what you can do.

Good luck!

I think it really depends whereabouts your endo or scarring is..I think if you relax and try different positions to see what is more comfortable for you,you will be fine xx

I don't experience pain with intercourse and never did. I had a 6cm chocolate cyst on my ovary, endo on my cul-de-sac, as well as the peritoneum, and bladder. So yeah, my endo was pretty bad and I had no pain with intercourse. I hope this makes you feel better or gives you hope! :)

I've never experienced pain with sex from my endo although if you try and have sex on the tail end of a flare up you could make the flare up worse

I do experience pain, cramping, and nausea after sex. My doctor thinks I have Adenomyosis in addition to Endomitriosis. But I saw your question about diet and wanted to share my experience is my diet change so far. I have recently started a gluten-free and lactose-free diet: essentially a "anti-inflammatory" diet. I also switched to tea instead of coffee (this was big for me). It's been about a month and I do feel a bit of relief in my stomach. My nausea has lessened in the mornings.
