First off:
"what about a coil for you? very, very effective, but reversible"
For me this is a load of rubbish.
I had a pregnancy scare due to my body trying to expell a coil - and we were both so appalled at the prospect of having an unplanned child that we decided that my DH would have a vasectomy. Luckily for us the coil did eventually do it's job and the fertilised egg didn't implant although it had done enough to start my body secreting pregnancy hormones which were picked up on a PG test.
I agree totally with ExpatinScotland that it is up to a man if he decides to have a vasectomy.
Granted, if his decision flies in the face of the wishes of his partner that is likely to cause a problem which will have to be addressed as a couple. However, I don't think that should detract from the fact that it's his body and his decision.
Actually Cardy, you have asked whether the decsion to have a vasectomy is a joint decision well, what about the decision to have a child? You say that you would't be overly bothered if you fell pregnant but what about your DH's wishes? When a woman actually falls pregnant you are no longer talking about it in the abstract and if you then decide that you want to go ahead with the pregnancy then where does that leave him? Where is your respect for his wishes?
If you have 2 children and he's happy to stop there why should you stand in his way of doing what he wants with his body?
After all, it's not like you haven't got any children at all is it?
In my view, the decsiion about whether to have more children is not something that can be compromised or bargained over - it's not like if I promise to never make you do the dishes again will you let me have a baby? It is just something too huge and personally I think it's morally wrong to try and coax someone into it, or to put pressure on them to say yes to it. People should only plan to have children if they're both totally committed to the idea 100%.
Oh, and finally, to the person who asked about vasectomised me and "man flu" I can say that my DH just got on with it and didn't fuss at all. He said teh procedure was painless and complied with all the pre-op care advice. He took a couple of days off work and had to lie flat for a day or two so as not to induce swelling and he had to wear tight pants too (!!). After that he went back to work and didn't really make much mention of it again.
I think if you've got the sort of man who routinely fusses about the merest thing you'll find he'll milk a vasectomy for all it's worth. Thank god I haven't got one of those. I'm the only one who's allowed to act the dying swan in this house!!!
