Mate I feel for you
I have had this feeling many a time and as others have said it takes time.
You have recently passed your test, Now the learning really starts and you don't stop learning, Believe me I have had a fair few "brown pant" moment's and thought to myself sod this biking lark. :-/

You will get there but as I say it does take time, and to be confident enough to ride with pillion takes some doing specially if its someone close to you [smiley=thumbsup.gif]

Take care mate.

I have sent you a PM mate [smiley=thumbsup.gif]
