I found after some time of discomfort that having tights on in general were causing me issue. I liked and had no issue with spandex bike shorts when I was younger but the last couple of years of active cycling it was causing me a couple of issues, most specifically chafing and discomfort in my groin. I swapped to wearing "gym" style shorts and a saddle with springs on my city bike and have had no issue with that manner of discomfort. I also don't ride the distances I did before, and not much recently at all. I really feel like there is something to be said for a quality set of shorts with a good chamois and in particular when riding long distances at speed.
