I have a Titan and have posted a study before on here about maximising the Titan's capabilities through twice daily cycling. I cycle for a minimum of 15 minutes each time and try to go more than 30 mins when I can. This is definitely helping.....I am about 140mm now and my shape is very good after initially being a bit flat in profile.
Arousal adds to this. At 6 months, according to the study I have another 18 months to reach full potential.
It will be fascinating to see whether I increase it.
As you can see on my signature I am 150mm flaccid which looks and feels fantastic, and a tad under 170 mm fully erect. I didn't go into this to get a larger cock, I wanted one that worked reliably. Interestingly I sometimes wonder about how blokes measure their equipment. I have posted pics on here in the name of transparency but haven't seen too many others.
Remember guys:
measure from the pubic bone along the top to the end of the glans, not along the side or underneath.
Most accurate way to measure girth is with the cardboard centre of a toilet roll after which you cut it so it opens out into a rectangle and measure with a tape.
