I think there is nothing wrong with it as long as your not participating as a way to hurt yourself.
Everyone has the natural desire to have sex. I've been thinking of this myself but haven't found anyone.
I'm bisexual and ended a 10 year relationship with a woman three years ago. I joke that it's been so long since I've had sex I'm not sure I would know what to do anymore.
I think I would be a guys dream - I must be like a virgin again!!
