BTC Variation
I haven’t seen this stretch posted anywhere, but I’ve been doing a variation on the BTC for a couple days now, even before I registered to the forum. The variation consists of being in a seated (or lying on the back) position, and reaching for the penis through the legs from behind, pulling the penis down and in the direction of the back, and then literally right in between the cheeks before sitting down.
The major drawback with this is that the penis has to basically split right through the middle of the two testes, which can be a bit painful.
Aside from that, is this an acceptable stretch, or is it not useful if not altogether harmful to the penis?
