If you are sure you never want kids then there is no reason why you shouldn’t get a vasectomy. Personally I wanted nothing to do with children until my 30’s and then I started to wonder if maybe having one might not be so bad.

I had my one and I can confidently say I am for sure done. I love my little monster with all my soul but there is no way I could handle 2 or more.

I totally get why you would want to make sure you never have any so if thats the decision for yoou then go for it. plus If you ever change your mind you can always adopt. I can tell you from first hand experience there are 1000"s of kid out there who need a loving home and not a whole lot of “loving” homes to take them.
