Quoting ~The Lunar Flower~:" No really, this post is about testicles lol SO has large testicles, so his excuse as to why we don't ... [snip!] ... them & tape it to his ass so they barely move. I guess I could check Pleasures or something to see if they would have something"
Not sure what you call large but my testicles are about grape sized and they hurt occasionally during sex too - to the point that missionary or doggy is painful. Testicles can vary in size at various times, temperature too, and they also become sensitive at certain times. Some days we might like it rough, other days cant bare to be touched.
Hope that helps.
