That's the only advantage I really see for you.

I never considered a vasectomy. I am in my mid (some might say late but fuck them) 30s.

I have planned with some partners and we just had a calm discussion about what would be the most effective and preferable method for her (some were more concerned about how long they'd have to wait after ceasing birth control to get pregnant, others were worried about weight gain, others it was more a personal preference like avoiding injections or avoiding taking a daily pill and potentially missing it).

When all else failed I relied on that Zidane-level ball control. One jumpoff I had insisted I nut inside her and she took the plan B after. We only fucked every couple of weeks but I can't imagine that was good for her. Her body though.
