We all finger our boards all day, I don't think the strength is the problem.
Then what is the problem?
sigh....
Well, back when I was still playing the game..
The reality of boy-girl interaction is dead simple..
There was sex, the end..
Girls are raised so differently from boys..
They each develop interests and hobbies that become firmly established in the teenage years.
So later on, when they try to do something together, the common thing will never be the MOST interesting thing that they've been raised to do..
For example..
Lets say a girl likes shopping for clothes (THE BEST)
Lets say a boy likes working on engines (THE BEST)
The apex of their interests do not cross..
SO, at best they default to a common interest that's only Mildly amusing to the both of them..
^^^ This hobby (whatever it is) will always be less interesting than SEX, and so guess what happens in the end..
They have sex.. and ignore each other from then on to go do their own things..
This is why the majority of relationships follow this the cycle where you get super close, then distant, then bored, and if without children, break up..
