The point again here is that the OP was already having insecurity issues well before any of this happened. This just happened to trigger the effect to an advanced degree. So basically, here's the resolution.. talk to your SO about what you like and don't like and it's ok for him and you to say "she's hot" or "he's hot" because they are after all.. in bed with you. It's pretty difficult to be creative unless you live in the fantasy world occasionally.
