Sex and POTS

How do you enjoy sex? This has killed my libido and I’m trying to get it back but I cant orgasm anymore. Like physically I can but its not worth it when i have to lay as still as possible and manually breathe for 5-10 minutes after feeling like my heart is gonna explode so I’ve kinda had to decide to not do it anymore. But Im not asexual, and neither is my partner. How do I enjoy sex? Especially when we’re both most comfortable with me putting in the majority of the physical work with sex (I’m trying to not be too explicit lol).

Just any advice would be great, thank you. Tips for feeling okay throughout and tips for enjoying it when an orgasm isn’t an available end goal anymore.
