First off, welcome to the board brah! Enjoy yer stay. As for yer question, research kegals. Also, learn to edge yerself. Edging is jerkin off a bit, then stopping. Jerk off, stop. That should help a lot. I'm assuming by yer username that yer 14, yah? As you get older, yer endurance will increase. Stay stoked brah! Once again, welcome to LPSG!
