PLEASE help im looking for the name of a song! please help xx?

I dont know any of the words to this song. Its a 70's 80's or maybe even early 90's song. The video is all i can remember. There are two people in it and they are on a beach. Its a man and a girl, the girl is really preety and hes singing about how much he loves her etc, its quite a sensual video, ITS IN BLACK AND WHITE, thats very important. I can remember that the girl does not have a top on but you dont see anything as she is cuddling the other guy. I really love this song, but i have been racking my brain for a year now and just cant remember it! I will give10 points to anyone who knows!! please help, thanks so much xxxxx
