This post is for (gay and bisexual) men only (well I should say anyone with testicles since intersexed and she-males have testicles. LOL) I assume many of you know how to twitch your testicle muscles and make your balls lift. (If not private msg. me and I'll tell you how. ) In the case of men with tight balls, it would be "inward" instead of lifting up. Anyway, I'm wondering who can do it, and if you can would you be willing to post a video or animated .gif, and give all of us a look at your sexy talent?
