Is it normal that this has a strange effect??

Found an old cartoon I used to watch for something I studied at school.

Around 14:15 they start, well, you know, so you might want to skip to that.

It seems to go on for ages, I think the way it's animated is really well done & the pictures of them flying around them are really pretty. The music's good too, but when she strokes his chest, and he closes his eyes in pleasure, I'm done; weak legs, stomach ache, everything. They're both meant to be teens aren't they?? Then again, it should be fine because they're not actually real people and it's a classic. What's confusing is that she looks just like a friend of mine – it's a running joke between us. i'm f too. Does this mean anything??
