Honestly, I like love scenes less and less. As a viewer, I don't particularly like watching people go at it on the screen. It makes me uncomfortable. I don't really like watching people french kiss on screen. I think it's much sexier and more of a turn-on if the chemistry is there and the sexuality is implied or hinted at.
Desire is always more exciting than watching people screw.
And that's what the old movies are full of. They could be standing seven feet away from each other, fully clothed and be completely on fire. THAT'S a love scene. So, I have done lots of love scenes, although never with nudity. And that's fine.
