Odd thoughts at climax

Okay ... So my boyfriend is downstairs doing a damn good job, I'm climaxing and I'm thinking of this girl that I hate but also find sexy.

I don't think I am a lesbian, I've kissed girls before and would like to experiment but have no desire to have a lesbian relationship. I am in a happy relationship at the moment but I've always had a wondering mind/eye. I find both boys and girls attractive, it's strange.

I'm just wondering is it normal to be thinking of girls when your climaxing? Probably not! It's not the sort of thing I can speak to my friends about either far too personal. I googled it and nothing came up.
