Yes- I shared this in another thread- I am involved in a group that meets for weekend retreats/discussions. we spend a lot of time sitting, on the floor. So I usually try to dress for comfort. one such weekend I usualy wear/wore walking shorts and boxers (less 'crunching up'). One afternoon I sat, engrossed in the speaker, comepletely unaware that my cock AND balls had 'fallen' onto the floor, luckily only the speaker and one other person noticed it. However, the womian had 'sexual issues' already and caused her 'quite a stir'. I was asked and from now on wear slacks AND boxers briefs (I was asked to wear a jock, but no way will/would I sit that long in that much discomfort.
We also have to strip down to bathing trunks or shorts, had a similliar problem there-solution is tho wear layers ie boxer briefs and loose shorts).
