After 2 years on T, my libido has finally kicked in. I have been with my boyfriend for over 8 years, and only over the past few weeks have we started having intimate encounters, but nothing that involves his bodily fluids mixing with or nether regions getting near mine. I have an extreme fear of pregnancy and no desire for children ever, and he absolutely respects this.
If everything goes as planned, I will hopefully be getting the internal parts removed in about two months, but I don't know if I can wait that long plus the 6 weeks healing time before taking the next step with him. I know that even on testosterone, although unlikely, I can potentially get pregnant. Reducing chances further, he has hypogonadism and is likely shooting blanks anyway, but he does not know for sure.
My question is, in addition to condoms, are there any forms of birth control or methods I can use to reduce the risk of pregnancy further, if I am not able to wait until after my hysto? I don't want to do anything that I will regret in the future.
I also want opinions of risk of pregnancy for a trans guy on T, a cis guy with hypogonadism, and condoms used correctly.
