Will it get bigger after 8 hours? Yes if it happens on a regular basis! But as it's been said, it is very painful in the later hrs. You could in fact make it bigger in say like in a 2-4 hrs erection, but this is only in a controlled way. You must find a way to get erect, and stay erect for 2-4 hrs, and you must apply DHT to your unit during this time. You also need to utilize a few exercises during the erection, such as balooning, edging, different types of girth work! When you hear of some men experienceing priapism, it is very painful if it last for a few hours! And also most men that have this condition, also have freaky cocks. They only get these freaky cocks, after having frquent episodes of priapism! Who knows how big you could get if you had the priapism, and applied balooning edging etc. I think that for the most part, it is very painful, and these men count the minutes away hopeing that their units go limp, and the pain goes away!
