The sexiest picture are those with some clothing still on. Complete nudes are boring because there is nothing left to the imagination. Here are some suggestions.
Silk cloth -- draped dry
Cotton cloth -- draped damp or wet.
Winter blankets bundled up with U hiding behind, so that it looks like U R naked
Big feather pillows with U sandwiched in between
Find a pool or waterfall out of doors on private land -- there are endless probabilities here.
