An implant will not increase your size. Certainly not significantly. It may even lose size.
If your penis gets erect and rigid enough for penetrative sex, there is no reason to go through the risk, expense and pain of implant surgery.
An implant will damage your penile tissues and render you permanently unable to get an erection without pumping up the implant. That is, you will be permanently and totally impotent. You will be totally dependent on the implant to get and maintain an erection.
It is possible to enlarge your penis by use of various techniques. Vacuum therapy, traction, etc can produce incremental (that is, small and over long periods of time with arduously applied protocols) increases in size. There is some risk if you get too enthusiastic applying these techniques. There are surgeries that promise quicker results, but they also have their risks. And beware of quacks hawking surgeries that are more dangerous than beneficial.
Better to learn good techniques for coitus or even good techniques for alternate sexual practices in addition to coitus. Cunnilingus is WELL appreciated by most women these days, absent religious or medical sanctions. Mechanical sexual aids (also known as sex toys) can add spice to a relationship as well.
