Question:
I read your response about pants not being Tzinut for women. Shouldn’t pants be immodest for men as well, since very often, especially when sitting, the male organs protrude at the crotch? Indeed, pants for men were a relatively modern invention originating in European culture. Previously, in all cultures, including Jewish, men also wore masculine style dresses or robes that covered at least the knees if not more. I asked several rabbanim this question and all I ever received was beat-around -the bush answers.
Answer:
You are correct, if the pants are tight fitting then there is a tzinut problem even for a man.
