1 - My elderly friend has asked me if I'd like to be talked "to an orgasm" over the phone. This has surprised me. Should I try it or politely tell him that although it's an interesting thought, I'm married and it isn't right? Physically, I'm tempted. Emotionally & rationally...no, and ta-ta.

2 - Is there a reputable and secure website that one can purchase erotica from? Suggestions?

3 - When I use a vibrator, I can bring myself to orgasm more than 10 or 12 times in one "session". Some orgasms are mild, some short, some long, and 2 or 3 are very strong/sharp. Usually after doing this, I wait a week or two before doing it again. Should I watch for de-sensitization or anything else when doing this? I don't want to prevent pleasure. (I'm kind of new, kind of rusty at this kind of thing, so the question is sincere.)
