Vasectomy? What about them?

So I'm quite educated on the whole cycle and family planning and BC options.ill be honest I truly don't want to use BC because of messing up my cycle and other negative side effects that seem to be common. I'm fine with using condoms and being aware of ovulation but I'm concerned about down the road. I'm strongly advised to not have babies due to a congenital heart condition. I'd risk losing the baby or having a baby with potentially serious conditions. I'd love to be able to pay for and have the operation of a disconnecting the tubes. But I've heard and read that it's easier for a guy to get a vasectomy than a women to get her tubes tied especially if she has never had children. Any of your hubbies do this? And what are their horror stories and side effects? Advice in general? I know someday I will be having a consultation with a medical team because it's required but that won't be until I'm married. And I'm starting to get curious. Thanks for the help!
