Stright girl usually masturbating to girls ?

I am mostly a straight woman in her early 20's. I have only dated men and had sex with men. I have made out with women before but to be honest it didnt do much for me.
The thing that confuses me is that
a.) I can pretty much only masturbate to videos of girls with big breasts. I've tried to masturbate to naked men but it just doesnt turn me on as much.
b.) when I have a crush (physical and/or emotional attraction) on people it's mostly been men. I've had crushes on two women in the past but they were both women who looked/dressed masculine and were flat chested (butch type).
c.) I have a boyfriend and he can make me wet pretty easily even just by kissing him or smelling him or hearing his voice. When I see him naked I think he looks hot but his nudity alone doesnt necessarily make me aroused.
d.) When I see a women with big breasts in real life, it doesnt really turn me on. I've been to strip clubs before the strippers did not turn me on.

Any girls relate to this situation?? Anyone have some sort of explanations to this??
I just masturbated to a video of grhisirl sexy dancing on YouTube and had an intense orgasm which left me super confused...(screenshot of the video)

 

Each to her own. We all have preferences.

 

I understand completely. Some years ago I discovered & eagerly embraced my awakening bisexuality as an avid bottom man. Though I adore everything two men can do to, for & with each other in bed, gay porn does nothing at all for me; when I masturbate (which is daily, at every opportunity!), I almost always go to 'Amateur wife anal homemade', and though I may wander to female masturbation, lesbian, or shemale solo cumshot compilation during a prolonged session of edging, I'll cum back to amateur wife anal to finish up... we all have our hot-spots!

 

So as a male I can’t answer your question. It would best answered by a more experienced female, That said, When you were in your teens did experiment with male and female. Looks like you need to find a balance.
My wife and I are a monogamous older couple, but talk openly and freely about all genre of sex. Find someone you can confident in to help you. My point is masturbation is health and should be done often. We still do. Whatever makes you horny and want to masturbate is good. It’s all good.

I'm na straight guy and assume what you are doing is admiring the beauty of the female form. Let's face it, many of the women in porn today are gorgeous.
