Things to watch for in a relationship:
I would say almost everyone gets into a relationship in which they are in love with the idea of having a relationship (after being bored of being alone) and do not look realisticly at whether they are compatible. (Even my dad at the age of 75 with his 4th wife!). I can kind of make myself compatible, just for a dream to live for a while.
The other common mistake to make is to note that opposites attract and look for the opposites in your partner and say, well I find them interesting now, but will they eventually annoy me
My favourite mistake was to ignore bad aspects of a person - eg stupidity, selfishness, alcoholism etc and quietly believe that I could somehow change them...aaarrggg
Fortunately loads of girls love TV's in my experience, I have always pulled easily, they feel much more at ease generally with TV's.
If everyone could fill out my lovely survey (currently the third crossdressing post), which is actually quite important, especially for all those teenage TV's ripping their soul to pieces wondering what the hell is going on with their inner selves... that would be great!
