I haven't been able to keep an erection for 30 years.  Doc gave me a prescription for one 20 years ago. It worked great.  Started the hobby because I love to suck on silicone tits, so I bought another so my wife wouldn't know and used it on hookers. Doesn't work for me any more. Neither does cialis.  Guess I will just pay $350.00 to suck fake tits and listen to there fake moans when I blow them.  Don't judge me.  We are all sick or we would not be spending money on them.

A 'penis pump' aka VED (Vacuum Erection Device) is not the same as a penile implant.  Not much subtle about using a VED to get an erection, though for most men they do work pretty well. Once you get an erection you take the VED off and try to keep the erection with a constriction band (aka 'cock ring').

A penile implant is entirely internal, and some single guys never tell their girlfriends they have one, and mostly the girls never notice.  Met a provider a couple years ago that had never heard of implants and was fascinated by mine.  After she understood how it worked she told me she was sure she had a client who had one but had never told her.

I have one and its great.  Not only does it not hinder 'enjoyment or pleasure', it enhances it greatly compared to not being able to get an erection.  No person in their right mind gets an implant unless everything else doesn't work. I agree that some men find it more difficult to climax.  I do, but I really don't think that's a function of the implant itself.  Actually the implant makes it much easier compared to climaxing without an erection.  Men who get implants have serious malfunctions, and difficulty climaxing is most often a result of their underlying malfunction or physical impairment rather than the implant ifself.  Plenty of men with implants climax without any problem and are in fact multi-orgasmic, since they can keep their erection indefinitely after climaxing.
