The 1st time I wore panties was more out of humor. She loves my ass and thought I would look sexy in her panties. I did it for a laugh, but she got so turned on by it, she started taking pictures, and I ended up doing a "fashion" show for her. It escalated to me shaving (light body hair anyway), then she started buying me panties and insisting I wear them all the time...to the point that she threw away most of what I had.
Finally, more out of desperation of having my "boys" hanging out each side, I found a great website that sells panties specifically for me, and cut to hold the package. For those frustrated by fit, but love the look and feel (yeah, I enjoy it..lol), you might want to check out bodyaware.
