Attracted to low hangers

I have been fascinated with balls, especially ones that are relaxed or as some people call it, saggy balls or low hangers, for most of my life. Any sac will do as long as its relaxed. This started with my own, I used to play with them a lot from a very early age, I liked how soft they felt in my hand. Then it went to watching heterosexual porn with women sucking on them, to then just looking at them on amateur sites. Now Im interested in saggy nuts getting a load on them, but the thing is I don't actually like gay porn, I just like seeing them all covered. I really like large natural breasts with a big load all over them, can that have something to do with it? I am not gay and I don't know if Im bisexual, the only thing on men that attracts me is saggy balls, nothing else. So my question to others on here is, "Is it normal to be into this fetish?"
