friendship interesting question?

Long story:am friends with this guy Alex whom I have knows since I was 6,we are both 26, he lives in Amsterdam working on his MA but his family is in Romania.I am from Romania but live in TX since I was almost 11 years old. I visited my grandparents every a couple of years in Romania and would see him and run into him and hung out with him.Ran into him 4 yrs ago,we hung out etc.This past summer I visited my grandparents for like almost 4 weeks,we hung out once,added each other to fb, are friends and getting to know each other,had a fall out due to personal reasons etc.We found out that we liked each other in Aug.'10, but the fall out occured,spoke 6 weeks later and are on amazing terms ever since. He got drunk on me once,getting all romantic while chatting on fb chat and well after that things went back to normal.He is finishing his MA in the summer and would like to move to the US in CA if he can...So 2 days ago I was chatting with him on fb chat, asked him how life was etc and he asked me the same to which I told him and then mentioned how I had a bit of some insomnia for 2 days. I then said how this duo/band which is techno would say in their song would say "I can't get no sleep" because the name of the song is called "Insomnia" which I thought was app.(we use music etc in our stories)...He followed it up with another lyric from the song which said " Tearin' off tights with my teeth"...I was confused with what he said but the convo moved on in a diff direction towards a diff topic.I was wondering what he meant by that lyric.To me it seems all sexual and in your face,sort of tongue and cheek per se. Thanks to anyone who can help me!

I am including the lyrics so you can look over them and make up your mind abt what he might have meant or the meaning of the lyric!_ingrid

I used to worry, thought I was goin' mad in a hurry

Gettin' stress, makin' excess mess in darkness

No electricity, something's all over me, greasy

Insomnia please release me and let me dream of

Makin' mad love to my girl on the heath

Tearin' off tights with my teeth

But there's no release, no peace

I toss and turn without cease

Like a curse, open my eyes and rise like yeast

At least a couple of weeks

Since I last slept, kept takin' sleepers

But now I keep myself pepped

Deeper still, that night I write by candle light

I find insight, fundamental movement, uh

So when it's black this insomniac take an original tack

Keep the beast in my nature under ceaseless attack

I gets no sleep

I can't get no sleep
