very weird question but i have 7.5 inches at 15 do you think if it stopped growing would that be enough?
I was in a similar position to you, mine stopped at about 7 (around 16). You're at the end of things where you might start worrying about it being toobig for the day to day, but I'm sure if you find the right partner you'll be able to more than satisfy them.
Also not a weird question at all, there's not a lad I knew who wasn't interested in penis size back at high school. It's just what you do at that age
Also it's better than a lot more than 50% of men. I hate to get all mathematical, but that would suggest that 7.5 is the average, which it is not. At 7.5 you're probably longer that around 99% of men. The distribution - as with all bodily features- is normal, with a mean between 5.2 and 5.5 and a standard deviation of about 0.6 inches. You can do the maths yourself if you're comfortable or use one of the many pages online. TL;DR 7.5 inches is massive, pornography and people lie about what is big.
