Being slightly vague incase the DM swipe for a boring article. Don't want outing.
I'm married to my partner. Have been for a good amount of time 10+ years
Both female. Me lesbian and her bisexual.
Sex life went off a cliff years ago but I put it down to her pregnancies and just life tbh.
Found out yesterday that she's only romantically attracted to women and is sexually attracted to men. Didn't find out from her so she doesn't know that I know.
AIBU to be pissed off that she hid this from me? I always thought it could be my fault she doesn't want sex with me, I have put a bit of weight on but nope, I just don't have the right anatomy I guess 
Good enough to raise a family with but not good enough to fuck.
