Try DLD Bends, in all directions. Do this 80 percent erect, lubed up while supersetting with SSG's. Want proof? Look at my pics in bottom link, my head at 100 percent erect in over 7". In the pics below I'm at 80. Warm ups are crucial, as are cool downs. If you have an understanding female besides you, hit me back, and I'll tell you how to include her as well! Great foreplay!
