Nobody here is going to give a 15 year old advice on getting an erection to have sex.

Talk to your parents or your doctor.

You're too young, so I won't give you advice.

You can't even spell maintaining, don't know that it's "an erection", not "a erection". "i" is capitalized, and not hard to do. "It's bad", not "it bad". And the whole "i have been trying to have sex with my girlfriend have can not keep a erection long enough to have sex imm 15 btw helllpp fast" thing, just makes me want to cry.

Stop worrying about your penis and start concentrating on school. Learn to write properly. Sex can wait, your brain is screaming for attention!

"alot" is two words, not one. This will explain it -- What is ALOT? (http://hyperboleandahalf.blogspot.com/2010/04/alot-is-better-than-you-at-everything.html)
