Vasectomy - How do I convince him?

Rosea
Since vasalgel is not yet on the market, hubby's only option is vasectomy in terms of birth control because condoms kill the feeling since he was lucky enough to have MGM at birth. He clearly doesn't want kids ever, but the whole operation on his man parts probably is why he hasn't gotten one yet. At the vasectomy clinic, he won't be refused due to his age like I have been for a tubal, the downtime is shorter, and it's much less expensive/invasive. Also, he has a varicocele, so I don't know if surgery for that would be necessary before or after. Any ideas on how I can get him to really consider it in the next 3 years?(my skyla will be have to be taken out then, I'm so done with altering my body over the years just to prevent children) - another female tired of bearing the brunt of contraception :)  for funsies, here's a pic of a mushroom I grew that looks like a little penis.
