How can i enlarge my penis?

theres gotta be a way to do it. im a big guy like 6'4 and im built big but my penis is really small im only like 6in long 4.5in around i have a really thin dick. Im tired of having to put off sex with girls because i dont want them to laugh at my thin short dick. im a pretty good looking guy too and i do good with girls which makes it even more painful/. i tried p.e exercises and it gave me erection problems is there anyhting i can do. ive been having a lot of suicidal thoughts lately i dont want to die alone because i got jipped in the penis dpt. if someone knows anyway to throw on some extra inches especially in girth let me know
