I just started last night as well, also using the Capt’s Wench.
I did 2 1/2 lbs BTC. The first set wasn’t to bad, but second set was pretty harsh(2 sets of 20 mins each). The way I did BTC is laying on my bed with feet on the floor with weight hanging between legs, while I watched tv.
I had a little trouble with skin acage last nite, but what ended up hurting the most was when I put the hanger on the second time I caught some hair up in it(ouch). Today I’m slighly sore at the base of my penis, and seems if I did hit the ligs some(can feel kind of a soreness beyond skin deep, is best way to put it).
BTW, don’t see how you did that much. Gonna stick with the 2 1/2 lbs for a week or so and see how it goes.
