It, like anything else, depends on who it is and my relationship with them. A partner is one thing, but a stranger is another! Even for a friend to do it would be embarassing for me!
Not very, I’d be embarrassed to be naked and examined that close and personal by anyone, except maybe in a medical setting, unless the doctor was an attractive woman comfortably dressed…
Female yes, it would be intense and although I have a preference for being the one ordering the female to undress and inspecting, I, m not averse to the reverse.
