Young fellas; as a not so young fella who some say used to fuck: Don't be a dick while thinking with your dick.
It's that easy. You be you, be whatever you're interested in, and just use your goddamn eye balls to read if the person is uncomfortable. If they are, smile and fuck off king. Keep it going; don't be a dick and watch that aura work and that dick get wet.
But remember, you have to genuinely not be a dick. Be yourself, be assertive or not, there's someone (many someones even) for everyone and never mind the bullshit rules 1 and 2 you self-deluded fucks.
Don't. Be. A. Dick.
You'll be happier, the people around you will be happier, and you will fuck and feel good about it while making others feel good about it. Simple secret.
