Lesboys?

For context I'm ftm. I've been seeing a lot of discourse on tiktok about lesbians taking T and it's been making me very... grossed out?

Apparently they call themselves lesboys and I feel disrespected due to the fact that there's such a big stigma around the fact that trans men are just masc lesbians. So these lesboys make me feel like they're making fun of or disrespecting us.

I don't understand nor process how a lesbian can be a lesbian but on testosterone. I don't know if I'm in the wrong or not. Anything helps because I'm scared I'm being transphobic.
