It depends on what "large amount" means. If it's no more than kissing and hugging or what not, I'll look away. Give them their time. (Public, of course...)
On television, I'll be more.. I don't care.
If it's more than that, in public, I'll feel a bit.. disturbed. If it's complete nudity on TV, I'm switching it off.
I do think it is just disgusting to view that.
