Okay here is the deal.... i normaly take 25-40 minutes before i ejaculate when i masturbate... hmmm a lil much rhyming... well anyways I figured I'd try not doin that for a couple weeks when I had a gf i figrued i'd prolly have sex with, well she broke up w/ me so i did it... and it took me less than 2 minutes to get off! my penis erected a hell of a lot faster & got bigger than it normaly does, but is that even normal after two weeks? i normaly do it once or twice a day...
Don't worry about it too much..... i think that's very normal... i'm havin it the same way.
