Painful sex (TMI)

Abi

So I’ve got to get tested for endometriosis, because I’ve struggled with IBS symptoms that now don’t match the diagnosis and one of that is painful sex. It’s not like I’m not horny enough, or turned on enough, but it’s ever so tight and painful and I’m getting tears and almost feels like lumps inside me. Can anyone give me any tips on how to relieve this??
