Hello! I'm extremely overdue to provide an update since these personal accounts aren't near as helpful if not updated at least semi-regularly. I apologize to anyone who may have been curious to know how I'm feeling recently, particularly because I noticed this thread has the most views on the forum. I'll be to the point. I'm 32 and it has been almost 15 months since my vasectomy.
Orgasm: I remain certain that the intensity of my orgasms has been reduced because of the procedure. This is not a psychological issue, it's a physical one. I will never accept being told by a doctor or anyone else that this side effect is not possible. It is and it happened to me.
Penis: My penis is not quite as sensitive as it used to be. I sometimes think that I lost a small amount of circumference as well, but will readily admit that could be psychological since I never measured myself before. @syberk1d has experienced a change in circumference post-vasectomy.
Testicles: Firmer, seem to change in size frequently, and lumps form at the base occasionally.
Scrotum: I had a varicocele on my left side pre-vasectomy. It became more pronounced (diagnosed grade 3) after vasectomy. It's not painful. Briefly considered treating it, but decided not to.
Generally speaking, I am quite happy and am having enjoyable sex with my girlfriend of six months. I am not depressed, though I sometimes think I could probably benefit from speaking with a therapist regularly. I still think about my vasectomy in one way or another very frequently - almost daily. In the back of my mind during and after orgasm, at least briefly, I sometimes think in a critical way about how it felt. Thankfully, thinking about how much I love the person I'm with typically overcomes any negativity. I rarely think about penis sensitivity; I'm essentially over it. Testicle "play" is less enjoyable than it used to be, and sucking on them must be done incredibly gently. The idea is more exciting than the actual physical experience, which is why it's still worth it.
All in all, I obviously wish I hadn't had a vasectomy but it hasn't ruined my life. It almost did, but I made it through. I am fortunate to not have chronic pain (I hope I never do), and I have sincere sympathy for those who do. I do not recommend sterilization as a method of birth control to anyone - male or female. When I tell a man that I'd recommend he not get a vasectomy, I always accompany that with that doesn't mean I would recommend his wife or girlfriend have her tubes tied. I wouldn't. I simply don't believe in it, and that statement has nothing to do with religion. It has to do with when you unnecessarily destroy the human body you're asking for trouble.
As always, if anyone has any questions please let me know.
