Just got a text form specsavers to say my glasses (vari-focal) are ready for collection, so today is the day i start to wear glasses on a regular basis (i'm gettin old

)
So what are the do's & don't's about wearing them?
Will they make me look more mature & sophisticated, will they help me attract the opposite sex??
btw - how about kissing? would i need to take them off whilst snogging?
