""TBH the way women "invite" sexual partners is generally by looking at them in the eye, and smiling. And responding positively when they engage in conversation with them. Leaning in, touching their arm, that sort of thing. Some more forward women might even approach a man they like the look of if they've had a bit -of-- dutch courage.
The clothes are irrelevant to this process also."
Clothes can make someone look more or less physically attractive, by enhancing or muting certain things. The level of one's physically attractive appearance can can help in such matters as increasing people's interest."
In the context of what I said, your response only makes sense if it means that the man should be wearing something that shows off his physical attributes, if he wants to maximise his chances of receiving interest from a woman.
Note the interest here is a look and a smile. An attempt to engage them in conversation might be appropriate in some circumstances, not usually on the street, except when the approaching party is pretty damn sure of mutual interest.
The interest being talked about on this thread is whistling, shouting, groping, following, wanking at, and so on and so forth. Towards children.
So in summary. What normal people do to be normal, ie trying to chat up an adult who looks interested (or at least not disinterested) in an appropriate setting, and leaving them alone if they ask you to = fine, really.
Following a 10yo down the street telling her you want a blow job, and not going away when she looks worried and distressed, and then when anyone asks saying "I thought she was older than that mate she's well tall and look at her legs" = not fine.
It never ceases to amaze me that so many men (and it is invariably men) claim to have zero ability to gauge the age of other people to the extent of not being able to differentiate between a 10 yo and a 25 yo, and zero ability to read quite standard human cues which mean you're making me uncomfortable, go away. And are yet strangely more than able to function in all other fields of human contact, in the workplace for example.
It's interesting isn't it. Almost as if they have a "blind spot" when it comes to interacting with females they want to fuck. Suddenly they can't be expected to understand quite normal standard things because they are blinded by a short skirt (or a medium skirt, or some long hair, or some big breasts, & so on). Even more interestingly, many of these men feel moved to interact with females that they don't want to fuck as well. And insult them. And even weirder, when a female from the first group has the courage to tell them to fuck off, they swiftly move her from group A to group B, seamlessly, and realise that they "don't think she's all that anyway". Funny, isn't it.
