I have a couple of questions regarding btc stretching. First of all, since I just started doing a routine (haven’t tried PE in about 2 years), is it to early to even think about this stretch? After all, it is a rather complicated stretch. Second, when I do this stretch, after following the video, I notice that my balls get in the way when I pull back. It hurts. I have to keep a leg up on the toilet or bathtub. If I try to put my leg back down, I crush my balls. Is this common? Something that I just have to get used to?
