Hello there. :d
1) how old are you?
This could just be a phase that you are going through. Or you may be bisexual. And well the obvious is you may just be tire of the same old things.
I am from australia I am female I am a lesbian I have never been with a man. I was diagnosed with epilepsy 7 months ago now, through my early years I was normal as could be neurologicly.
So to your question I dont think that it does. But it would be interesting to do a poll on it wouldnt it. I know that my neurologist once said loose your partner(lesbian lover) and your epilepsy will go way.
