Finding quality, sexy, model-released images is more difficult than in sounds, especially with a topic as narrowly defined and "males for Valentine's Day". I shoot girls for calendars, but that's a fairly broad, widely used subject matter. Wish I could help, but I quit shooting men many years ago. You could try a friend of mine here in LA, if anybody has what you need, it would be him. And no, he won't be real cheap either. http://www.artminds.com/
Tell him I referred you, we often refer clients to each other.
BTW, the major legit stock agencies (Corbis, Getty, etc) want no part of sexy images - its not politically correct or something I guess.
