My take as a dude with a vagina who has done things with people of different genders:
Vaginas aren't gross. Probably LW would do better to just say "oral isn't my thing" and leave the "gross" part out of it. (I, for example, do not like receiving oral because it intensifies my dysphoria in ways that penetration does not. There is a way to refuse and still be polite.)
That being said, nobody should feel obligated to perform any sex act on anybody. People are allowed to feel uncomfortable with any sex act for any reason and say no to giving it or receiving it. "Just use a dental dam" isn't necessarily going to help, as there may be issues there besides the taste (while I'm not saying LW shouldn't try it either; that's up to LW).
I also feel like people need to stop with this identity policing shit and stop saying someone is a "fake" whatever because of certain unwritten rules about gender/sexual orientation performativity. For fuck's sake. We get enough judgmental crap from non-LGBT people, this thing we have with eating our own (hurr) needs to fucking stop already. Nobody is a "fake" bisexual because they don't like performing/receiving Sexual Activity X, you shallow, judgmental fucks. (Not "you" directed at anyone here.) If someone wants to call me a "fake" such-and-such because I don't like doing Thing X or Thing Y, there are issues there well beyond sexual compatibility and I ain't got time for that, bye.
somewhat TMI, sorry
