re: Vasectomy preparation, what to know?

Good responses guys, glad to have a good idea of what to expect. I trusted my doctor for the most part but you know how it goes, it's good to hear from people who have actually gone through it.

I want to change the perspective a little bit. I imagine most of you all have done this as a form of family planning. Essentially that you all have done this after having children and after deciding with your wife that you all are done having children.

I am single and have no children. I am doing this because I do not have a desire to actually have children. I want to be more sexually active without the risk of an "accident." Obviously it's not something you share with people unless you want to, but do you look at it as weird that a guy would have it before being married and/or having children?

Also for those of you who are unmarried (either single, divorced, widowed) and have had a vasectomy, did you get a sense of freedom after the procedure? Did it give you a sense of power knowing that you absolutely know you can not get a woman pregnant? Did you start to have sex more often with random women after getting a vasectomy?
