The disadvantage of live display is that the people are unlikely to look as good in leather panties as do the models on the Internet. Plus, you have to be polite to them and ask if you can watch — in short, you have to talk to them. The advantage, of course, is that you do have to talk to them and thus might make a friend or find someone who is neither your husband nor the ghostly afterimage of your husband with whom to do S-M. This is all very hard work, and for the confirmed introvert it (speaking) will never come naturally. But compared to being alone, lonely, haunted, and unable to masturbate, it's got to be a breeze.
Love,
Andrea
