As a nudist it has been noticed running down my leg after we have returned to the poolside. It was no secret about where we had been and what we had done. It was never there for long as we always swam afterwards.
I have occasionally been asked for my pants after a date when I have saoked them after a leak back. I always asked that they be returned (laundered) or replaced. More often than not they are replaced with the request that they be refilled. I must say most have been very sexy and a pleasure to refil.
