Monkey, you're still very early on in the collagen remodeling process. As other guys have reported it's not uncommon to have discomfort with even erections, or pain or swelling after sex or manipulation. It doesn't always happen, but I from what I've read it's not super uncommon. I would continue to take it easy with anything that potentially aggravates the area. We need to remember that it takes a few months to fully heal and replace the filler with collagen. I wouldn't worry too much about your current situation unless the pain is paired with noticeable inflammation, warmness and or a fever. My guess is it's just growing pains.
