Sex and endometriosis

So I’ve been hesitant in posting this as I’m worried I could sound crazy😂🙈

So I have recently come out of a long term relationship and have been diagnosed with endometriosis for 2 years.

Me and my previous partner rarely had sex and when we did I could never reach orgasm. However, I am now with someone new and can easily reach orgasm.

My previous periods were unbearable. I couldn’t go a period without taking a handful of prescription meds. However, Sunday I came on my period (my first period since having a new partner) and there has been absolutely no pain with this period and a much lighter flow.

Could changing partners (and their size🙈) have an influence on my period/endometriosis??

-I’m not on any contraception so i can’t put this down to hormonal changes-
