Well as a frequent woman blood donor, they would ask if I had slept a gay man etc, but not ask me if I had slept a gay woman.
The reasons for this is primarily that Aids is primarily transferred from male to male/female more frequent than it is from female to female/male.
I believe the woman to woman/male transfer is THIRTY THREE times LESS likely than that of male to male/female.
It’s far from certain that a woman would know about every sex partner of her sex partner(s).
