Of course it differs.
What humans like differs whether it’s Male or female.
The point is a woman is more likely to know where is more sensitive on another woman, equally a man is likely to know the same. As we have the same anatomy.
That’s just logical.
It’s not about ALL people like the same thing, that’s ridiculous. But it is a fact, you know your own body better than anyone else, so are likely to be “better” at something on the same gender than the opposite.
I don’t agree that blokes are “straight forward” nobody is straight forward. Some men will like to be wanked off vigorously, some slow. Some like pornstar BJ’s, some like face fucking, some like teeth grazing their shaft. We might be a simple gender but we aren’t straight forward.
We ALL like different things. I personally like a vigorous hand job with two hands, as can be seen from this thread some punters do not. Which proves we are not straight forward.
