Blogger333, First let me say that I love your posts and look forward to reading them, they always make me smile. To say whether or not you have low swingers as you put it, and no pun intended here, but whether or not they swing low or ride high and tight is in your genes.
Being a woman who happens to love ummmm, balls, as they fascinate me, I tend to take notice of the boys. Many men die in their 90's with remaining "high and tight", while others have low swingers all along. Now, I will admit that along with everything else on our bodies, gravity does take it's toll. So it's not surprising to me that you are noticing a little sag, but if you expect to be fishing them out of the toilet in a few years, probably not going to happen. Sorry.
