Glad you’re getting comfortable! As your mileage and frequency progress, the opportunity to get “real” saddle sores may actually increase. I’ve ridden fairly consistently since 2001 with a few long periods off the bike. When I start up again, I often forget a few of my basic rules - one of which often brings up an infection based saddle sore. As long as I never wear a pair of cycling shorts more than once before washing I don’t get saddle sores. I’ve often worn a pair twice without a sore, so the relationship is not fixed, but every sore I’ve developed has come after wearing shorts twice. So my advice is get several pair of real thinly padded shorts and wash them after every ride! YMMV.
