What your preferences are in bed are personal, but ring fingers longer than the index finger indicate more testosterone for both men and women and they tend to display more masculine behaviors such as aggression. The condition is caused by hormones in the womb and predisposes women in particular towards homosexuality. Others have suggested smell is a better indicator and that people are naturally attracted to potential mates with radically different immune systems than their own.
I think it is a two way thing, if you both feel a connection it's easier to trust and fully let go, well for me it is.
can you tell by a person's picture. you have a special gift :-)
How do you test it out?
can you guess how i am in bed? you can ask me any question youd like.
