sexual what?

when we look at sexual identity we seen gay or straight but naturally we dont choose to be that way as some religious people seem to believe. once of my pet peeves is that people believe the nature vs nurture where you sare influenced by my things in your life...ya okay..if we are influenced by our environent we'd have alot of nuns running around then, the idea behind sexual identity is who we are and how we feel about the different sex. including the idea that gender and sex dont go together ex: the pregant man... although our society looks at sterotypes in all different ways being gay or straight we are human so lets follow that equality rule!
