As per my personal experience it will surely take your relationship to next higher level... First kiss is really really unique..by the way if you both are first love for each other then OMG i cant describe it in words..

All works only when its done in the proper manner..I took two weeks training to make my first kiss perfect and it really helped...but the funny part is that though relationship was very strong , did not last forever..but gave a book of beautiful moments to remember.
