Is it true most men lose their vaginity to a lesbian?
As US census data indicates that only 3.8% of the population are LBGT the necessity of these few having opportunities to "service" 50$ of the American population is pretty low. This doesn't even address the low opportunities for them to meet, the big question of why, and the world view of people that lie awake at night wondering about this eventuality will not be addressed.
Well..this isn't theoretically proven,, so the answer is: no answer. But a lot of guys do like lesbians because they are hot&they sure can do some wild stuff. On the other hand, other guys think it's entirely gross and will never date a les. It's all about your choice.
The majority of young women are not lesbians. It is generally mid teens that a young woman knows if she favors young women to young men and it will take a few more years to be sure that she is a true lesbian. If you have decided you are a lesbian then yes, you can be a lesbian sister to your siblings.
Since there is absolutely no evidence that vampires exist, I would have to say no. But, if you are asking about the fictional world then I would say yes. Vampires have forever to explore their sexuality so it is a fair assumption to assume most of them are Bisexual. In the True Blood books (by Charlaine Harris), the Vampire queen of Louisiana is portrayed as lesbian.
