When i found pe my goal was 12”, than i found that this size is ridiculous, only useful to fuck elephants. Im 7,5” too and my final maximum goal is 8,5” NBP X 6,5” MG (a mandingo size). I have 20 years old and i expect to reach that size in 5 years. Yeah, im very patient. Just look at a ruler, 10 inches is useless, you need a excellent and healthy blood circulation to maintain a erection at thas size. Soon you will find that 8 inches is the perfect, huge and monstrous usable size.
Do a newbie routine for 3-6 months, be patient, than move to clamp and girth exercises. In about 2 years or less (being realistic) you get the perfect size. Is just in your head bro. Look for vids of mandingo, the biggest in porn industry. People claim that he is 11-14 inches, but in real he is 8,5-9 NBP, you will see he has many trouble to fuck the girls…
