I cant think of any reason why its not a 'do-able' plan but it just a wierd plan to me. Is it the whole idea of other forms of contraception that you are against? Are you allergic to latex? You dont trust the woman you are doin it with well enough to let her handle the BC on her end? Theres methods out there that are 90 plus percent effective when used correctly, you need to go through all that just to get that extra 10 percent? I mean really, why dont they just send pre teens off to the sperm bank and the surgeon before they hit puberty...no more unwanted pregnancies..problem solved.
If I was dating a guy and he told me this, he'd have to come up with a pretty good reason and answers to these questions in order for me not to dump him for being a wierdo.
thats just me tho, i've got myself..one wierdo is enough
