Now I know i'm not really one to give advice as i am useless, as much as this may be true i'm not stupid. If you don't believe me then watch the way that your friends speak to there significant others. The relationships that last tend to consist of the two getting along like best friends, those that fail are usually when the bloke slowly goes back to himself after he's got them hooked, and they realise he is a complete dick.
Confidence is a hard thing to gain, you can spend ages building it just to get it shattered in a day. You could build it by having a 'standard', but as you will later come to realise, these never work. You could start at the bottom and work your way up but then who wants the reputation of the lad who gets with anything that moves.
There is no simple solution to a lack of confidence its something that has to grow over time. You can try having a 'standard' but in my experience, they don't really help. I truely don't know what to suggest, i spent all day wondering why i have no confidence, and came to the conclusion that there is no reason to. See thats not my problem, I know i could do it if i tried but I don't because i'm to scared. And i'm guessing its the same problem with you.
So i'll leave you with this, don't be scared, just fucking do it. It maybe easier in theory than in practice. But if you give it a go so will I.
