Mannn you're going to have so much funnnnn!!
Excited for you!!
Just remember to practice safe sex out there
I'm currently dating a 37 year old, so I don't know if that's too old for what you consider old
tl;dr age isn't a factor and all but 1 woman I've been with out of maybe 12 have been very satisfied and came back for more and more and mooooore
Since I was implanted at 34 (I'm 39 now) I had a few romps with a girl that had just turned 21 and she kept coming back for more before I moved on... So I think she enjoyed it.
There was a handful of women in their mid to late 20's.... Like 23 to 28 years old and they seemed to also very much enjoy it to the point they wanted a relationship to keep my dick for themselves....
Then another handful that were in their early to mid 30's and they also enjoyed the performance of my implant.
The one girl that wasn't satisfied, was my girlfriend at the time of my original implant (she was 33). She felt my original Viagra-induced dick was better and the implant didn't feel the same. (She didn't know that I had been using Viagra for almost our entire relationship and it was no longer working)
I also had a slight upward curve due to peyronies prior to it being corrected with the implant, so she may have liked the way it caught on her g-spot.
She was the only one that ever had a complaint about the implant, and she was still ready to marry me regardless of it. Suffice it to say that didn't work out and I ended it.
Any other questions feel free to ask!
