did I make a mistake by letting a friend know I had surgery?
My answer is that is not a good idea to tell friends about the implant. It is just too juicy and irresistible for gossip. the only person, in my opinion, who should know about the implant would be the person you are having sex with.
Now, for those of us who occasionally face the situation where answers are demanded regarding why we were "out for a week", there should generally be enough respect from friends/acquaintances to back off the moment you say "I had some urological surgery", but in the case that there is an inqusition, I think it is OK to disrespect those inqusitioners with the following white lies:
1) " I had a hernia repair "
or
2) "I had urological surgery " ---> "old man plumbing stuff" ---> "operation in and around my prostate for benign problems" ---> "removal of a benign lump on my testicle"
or
3) for medically savy inquistioners "i had a cystocele repair"
By the way, what do you do if your one night stand fondles your balls and detects the pump ?1) "yup" I have had some work down there. I am now totally normal, and you will not notice anything different except that I get harder and last longer than any man that you have been with. And then when the girl says "umm what do you mean" you can answer "well, for example, I am one of the few guys who can have multiple orgasms" and then let the lovemaking begin.
or
2) that extra ball down there, it is called a "door knocker" and it is supposed to make doggy style sex more pleasurable for the women as the knocker slaps up against her butt (I got it when I was younger in the phillipines) "Let's try it and see what you think." And then, when she says it doesn't seem to make much difference, say "I think it really feels best once we have been thrusting for 20 minutes doggy style, so lets keep trying" (by the way, implants like that in the phillipines are called BOLITAS)
or
3) for medically savy detectives: that extra ball down there, it is residual medical coils and plugs for a "varicocele repair"
or
4) for the stubbornly accurate inquisitor detective: "yup, i had some work down there, it's a little pump and it means that I get harder and last longer than most men; and it means that my dick will never fail you, ever. It also means I can adjust how hard I can get, go ahead and feel; if I am ever too hard for you, I can back it off a little. Let's play and see what you think.
