I got this notion which makes sense rationally that telling a girl you have a vasectomy is a huge turnoff. Like there is some instinctual excitement at the prospect of getting pregnant for a girl. Anyone want to weigh in on those experiences?

I'm thinking of doing it to protect myself through my youth but freezing sperm beforehand in the off chance I ever meet a girl worth starting a family with. The thing is I would never tell a chick I'm seeing about this unless it actually came to trying to make a baby with them (or if they tried to trap me with some other guy's spawn). I could see that revelation fucking with the prospective mother's head and then every time we fuck thereafter there wouldn't be that excitement. I understand the need to balance my own self-interest but I'm wondering if this is just in my head and I may as well just tell chicks early in relationships.

Also I am aware of vasalgel, but fuck waiting on something that looks less and less likely of ever becoming a thing.
