Curious

So I am in a very committed relationship with my boyfriend of just over a year now, we like to try new things in the bedroom and we often watch porn together. I have never had thoughts about me being with other females and I’ve never had the urge to try but I’ve noticed that I like to watch girl on girl porn, especially when they are concentrating on the breasts. It turns me on quite a lot when I see women playing with their breasts or each other’s breasts. Is this unusual? I do also enjoy my breasts being touched, played with etc so do I enjoy watching things like that because it’s an area I like to be touched?
