Concerned my ball stretching fetish is now considered extreme?

I dont consider myself gay or bi. Standard sex has diminished with the wife, age? We're senior citizens now. I started tying up my balls a few years ago and have used stretchers to make them hang lower. I realize this is my thing and not trying to impress wife or anyone else. Wife not amused. I'm not into anything anal, eitherside. Not into dick expansion, cbt, ballbusting or saline infusion but have vacuum pumped my scrotum to 12 inch softball size a couple times. I like the feeling of low hanging big balls. In using metal weights and stretchers has gained me several inches in hang. I do like doing this regularly to the point where I guess I'm considered an extreme stretcher. My concern is has this gotten out of hand and considered abnormal? Do I need seek some sort of help? Who would I go to for this type of thing?
