Hey… Ronnie here… Perhaps my story could be of some help to you
For the past 6 months or so now I’ve been a member of this penis enlargement program website which has worked amazing for me…. I’m 1/2-1/2 japanese/chinese.. and unfortunately, at least for me, the steriotypes about asians rang true.. after I hit the end of puberty at like 18, I was about 5″10 height(which btw is pretty tall for most of asian ethnicity) and downstairs I was only 5 inches when fully erect…I did some research and found out that I was almost 1 1/2 inches below average… However ive had about 3 girlfriends and the first two never complained or said anything about it, so i always assumed everything was fine. This was until my last girlfriend who was a total *****… Her I was with for like 4 months until she broke up with me, seemingly for no reason… So when i asked why she had done it she snapped back at me saying how she could no longer “put up” with me or my “baby dick” .. I kind of just shrugged this off because I didn’t really care all too much about the girl anyway.. but the latter of what she said stuck with and ate away at me inside.
So eventually I came across this one penis enlargement website that caught my eye and i signed up for it.. Over these past 6 months using all the material and support in their member section… i’m now measuring in at just a little under 6.75! It’s definetely not as much as they told me i would gain in that period of time, but im still more than satisfied… because now jamie can take her stupid lil insults and shove it. lol ANYWAYS sorry for the rambling, their website’s .. http://www.penisadv.pcti-system.com .. and it’s basically a natural way of enlarging your penis through various different “exercises”… the science behind it is something to the effect of destroying cell tissue in the shaft of ur penis through specialized exercises, then not like-but similar to a muscle… when it heals and rejuvenates- these damaged/killed cells grow back larger, therefore expanding your shaft… whats interesting too when you research into these special methods these exercises and so forth, will see that these are actually what ancient indian tribes used to do way back in the day to enlarge their penises. Hope I was of some help to you my friend, and I wish you the best of luck!
