just a quick line to add my twopence
i got it done myself about three years ago.
no problems since just great sex, spur of the moment stuff lol
i would suggest you get it done on a thursday or friday and you can have the weekend to r&r as you may need it. (feels like you got a unreal kick in the you know whats ohhhhh)
Personally i got it done on a friday and had to go and do site work on monday, man i was sore, thought monday would never end lol
all good now though.
feel free to drop me a line if you have any questions though i would warn you i not a vasectomy expert i was only the patient.
