Nervous wreck cant get boyfriend help?

many people find me attractive, alot of times ive been told im pretty and otherwise from strangers,friends and guys therefore i can easily attract people... the problem is that im always nervous especialy around boys. im a really nice person and have a good sense of humor but i can get so nervous i would shake a little and most of time i can turn out clumsy and fidgety from the whole thing. im afraid to go on dates for this reason... i was in a relationship a couple months ago and i really like this guy but because i was so nervous around him i could barely talk to him or touch him then have this awkward silence and when he would kiss or touch me intimately i would laugh to ease the tension. im 18 by the way
