Labels are useful for identity formation and for Communication to others.

If you're extremely unlikely to ever settle down with a man, you can call yourself a lesbian. It's an easier way to explain to men that you are not interested in them , than going into a complex discussion of, "well, I could have sex with you, but I am not really interested, because you have a penis and all the other features that go with it ."Quashes false hope and prevents false starts.

Sex is sex.people have it with people they are not attracted to or interested in all the time. It doesn't indicate anything about who you are, or who you are attracted to, unless those two happen to have a meaningful correlation.

Even a lesbian would use a Love Machine since they have girl genitals....so if you are being used as toy,you can still penetrate
But if you talk about emotionally and romantically pleasing her that's self contradicting.....Can you drive a boat on a highway.....no boat drives on a highway

The most important sex organ is not the one in between your legs. It is in your head. It is your brain. Men and women look different, they smell different, they taste different, they feel different.
