Why do you feel you need to? That is a personal decision and personal actions, and really doesn't involve them, imo.
You appear to have already told your mom at least. Is it validation you're seeking? It doesn't sound like she is going to give it to you.
I don't understand why saying a guy (on the street) is cute would be a lie because you follow such a lifestyle.

Why wouldn't guys or gals be cute or not just because they are cute or not?
TC of yourself. I don't think now is a good time to make a statement. (((hugs)))
