Easy there, headshrinker. First of all, not Lord Harris, not me, no one here can say how long it would take for you to get these gains. Second, don’t think this way - how long will it take. That’s a good way towards an injury, because it shows impatience. I understand that, we’ve all been there. But PE is not a race, it is a marathon. So arm yourself with patience.
Lord Harris speaks judging from his own experience, I presume. But keep in mind that we are all different. Some guys gain length easier, some guys girth, some have trouble with both.
I hope you are an easy gainer. But you may not be one. So you better be ready for hard and patient work. Did I tell you to be patient? I can’t stress that enough. Gains will come friend, believe it.
Concerning routines, start with the newbie routine, get conditioned and familiar with your penis. After a few months you can start with the advanced exercises and see how that goes. Just go easy, so to avoid injuries. You want your dick to become bigger and stronger, right? Go easy, go gradual. There are no fast easy tracks in PE.
Take it easy and happy gains!
