I don't know why 'involuntarily celibate' people of either gender need a catch-phrase such as Incel to identity their situation. That implies group membership, and that implies being complicit in what the group does as a whole. You can't go around saying "I'm celibate, but it's not voluntary, but I'm different than the other people who are celibate and not voluntarily for these specific reasons ...."
You don't need to print and wear your status on a t-shirt, or something. Why then (with all due respect) do you need a name or word at all? I wouldn't go around wearing a shirt with "VIRGIN" or "LOOKING FOR SEX" or "LOOKING FOR A RELATIONSHIP" on it. In what other capacity is a word such as Incel needed? If you don't meet a person then the word wasn't needed, because you aren't informing anyone of your status. If you do meet someone, you have a private conversation during which you say either "I'm a virgin", or "I haven't been in a relationship before", or "I've not been sexually active". Those are mature ways to express what's going on. A catch-phrase does none of that, and as such it isn't necessary. Real people need real communication or they will be grouped accordingly by the subsets with which they identify. In this case, that will not help your situation at all.
