some straight guy i was friends with was obsessed with me. he only cared if i liked men and had a bf for some reason, and would ignore that i liked women. he would act like i was straight and that if i dated women, that just meant i was single and obviously interested in him.
he was a friend or a loved one? No one I have been really close to has been gay that I know about but certainly had some acquaintances and I can’t imagine just ignoring a girl is gay and trying to get into her pants. some folks don’t find marriage much of a turnoff though so maybe they would find gay not much of an impediment. Although your saying he was concerned if you had a boyfriend so I guess that was important to him. I have had gay guys suggest stuff but it always seemed in jest and not creepy.
he was an online friend who was attracted to me
personally I don’t take online things to seriously. not sure if I can say anyone I have not met in meatspace is a friend. just acquaintances really.
