Yes, we understand completely from your other posts that you have little knowledge or understanding of safeguarding for children or young people.

Exactly - every time anyone (man or woman) finds someone visually sexually desirable they are involving a stranger in their sexual feelings.
This is a case of exhibitionists using children and adults in their sexual fetish in a public place. If you are fine with being part of someone else's sexual fetish being publicly performed without consent, that says all anyone needs to know about your own sexual boundaries.
