Firstly Newbie, let me say having an implant is a whole lot more fun than pills, pumps and needles.
Changes? One of the most dramatic, noticeable and immediate effects of having an implant would be flaccid size. I, like many other men was formerly a grower......now I am a show-er.
My deflated cock is a tad over 6".....all the time. Is it an issue? No, the more time goes by the more it feels 'right' ......in other words I have gotten used to it and love having a permanent 'package in my pants.
I am at the 8 month mark now and pumped up I am about 6 3/4" and around 5 3/4" in girth. My girth has increased over the last couple of months with twice daily cycling.......I continue with that program because some research shows success at increasing girth and possibly length(I don't have a sense my length will increase but almost 7" will do me!).
The biggest change though is regular and lengthy sex sessions with my beautiful GF the divine Miss H. It is amazing what a change it has made for me being able to have an instant and then constant erection. Yes it feels good, the sensation is still there although it has changed a little and I think that is partly because of the implant and partly my age.
Gotta go now........ask specific questions....easier to answer direct questions
