I ended up having to have a full hysterectomy for mine

Listen to your body and try not to expect pain. If you have pain during intercourse it may be different pain than another person feels or that you feel another time. Or you may not have any pain at all. However, if you’re tense and expecting pain then your body/ pelvic muscles will guard against intercourse and subsequently result in pain. As a precaution, use lots of lube. If you’re familiar with techniques to relax pelvic floor muscles, do those (if not, consider seeing a physical therapist, they’re an amazing alternative/addition to traditional treatments). If you do feel pain during intercourse, listen to that and do whatever your body needs (I.e. more Lube, change positions, continue with non-penetrative sex, stop altogether). Don’t just push through the pain. You can also give yourself an abdominal massage after to calm things down down there, especially if the pain presents like cramping afterward. It may also help beforehand but I’m not sure. If you do feel pain keep track of the pain - where, when, what kind of pain, severity, etc - that way you can ask your doctor/PT about it and they may recommend personalized options to reduce or prevent pain. Good luck!

If you don’t want to try medications or anything surgical to help the endo itself, my biggest recommendation is pelvic floor PT! It totally changed my life. You can also use dilators or a wand, but they are best used with a PT. I also recommend the Ohnut, it stops deep penetration and will help as you work on other remedies!
