Sexuality questions.

Sometimes I think I missed out on girls. Im married, to a man, I love him so much. But I sometimes find myself wishing I would have stuck with girls. I have never been with a girl, but I was in a relationship with one. It ran its course, nothing major.

I'm just really confused right now and I am not the type to have a threesome. So I don't know how to fulfill these urges or whatever you want to call it.
