Tina, to me, part time means 1) occasional cross dressing and certainly less time dressed than in full guy mode. But more to the point of informing others, do you need to be dressed in their presence? If yes, then tell them. I dress a few times a month at most. I never choose to nor feel a need to dress instead of doing things with family and friends. So, my cross dressing doe snot affect them in any way.
