Is the song High from the Band Lighthouse about Sex? ?

Question

I remember to listen this song when I was a little girl in the 90's and I got a long time to find it. I could not remember the Lyrics. When they sing fly in the sky of Love, do they mean sex? If yes, I am ashamed to like this song as a kid. It is not for kids. 

Update:

I come back in time when I listen this song. It is very strong in my childhood memories.
