I have a question for DU GLBT members, if I may

[Emit]

An 18 yo family member just recently came out to her family and close friends that she's bisexual. Soon after, she entered into a relationship with a young woman her age. I was ecstatic that she seemed so happy and comfortable with moving forward, as this is the first girlfriend or boyfriend relationship she has ever experienced. (She's been on prom dates and such with boys but never had a relationship and the dates she's been on were more friendships - never a sexual interest, she says) They went to the prom together this weekend - she went all out with corsages and all. Friends and family have been very supportive.

The problem is, today, she is really down and tells me she does not want to be in this relationship and I suggested it was just moving too fast. Upon further discussion, however, I asked her if it was this particular girl or if she was questioning whether she wanted to be with girls, in general. To this, she expressed a great deal of frustration and tears and said she just didn't know for sure. She said she has known she was attracted to both males and females since she was young. She said last night at prom, she would've preferred to be with a young man - no one in particular, though. She said most of her attractions to females has been to older women.

The question I have is, is this common for bisexuals to continue to question their sexuality throughout their teen years and into early adulthood?

Fwiw, I told her that I had a real problem with commitment in my early adulthood, something I called, "No one wants to belong to the club that will accept them as a member," and we discussed how our own insecurities/lack of confidence can often screw with us when we try to commit to relationships. I suggested that what she might be experiencing in this new relationship has less to do with gender than it does to committing to a relationship.

With the usual complications teens face with relationships and sexuality on top of the questioning of the bisexual nature of her sexuality, she seems really confused. Any words of wisdom? I went to the library today, and did some research on line about teenage glbt and questioning issues, but didn't land on any good literature/sites yet. Any pointers, recommendations I can pass on to this young woman?
