This is aspect is confusing and discouraging. Any solid methods?

I like being a kind-hearted nice individual and know when & how to instill limits.

BUT when in the field or gaming I’ve got no clue how to maneuver or tell the difference between the two.

Too mean and girls claim they don’t like it or are generally turned off by it, but sometimes when treated like shit they reciprocate in a positive way.

How to balance? What are some DO’s / DONT’s and pointers.

Thanks in advance.
