I would never discribe us as sick, perverted maybe, we have an unusual hobby which we both enjoy.
Do we care what others think? well yes we do actually we take all efforts to ensure others we know are not aware of our LS.
I have come across some at work that have admitted to being into this LS and are then belittled joked about, and in general made fun of as if stupid, the two blokes that spring to mind were not actually cucks simply mugs who had wives who treat them as such, years later their admissions are still talked about so new staff can laugh too.
