I take it you have not been doing pe for long. What does your routine look like. I would start off with lighter tension on your stretches and work your way up till you are not sore anymore.
Is it becoming red and aggravated? Swollen a bit? This can happen when too much pressure is applied. Cushioning your grip can help quite a bit, using leather golf gloves or the work out gloves, grip is much more comfortable. So guys will used a prewrap of a soft cotton before gripping, putting a buffer between them and the skin. Some even find rubber gloves, like dish gloves help with this.

Wow, that's a pretty thick frenulum !
I got rid of my frenulum using a technique for tying it off. Have a look at the thread titled "Frenulum Tying" - it might work for you, depending on how much time you can take off of Penis Enlargement. Might take a month or two, but most guys seem happy with the result.
