Able to take place in the heat of the moment. Cybersex sex by email or chatrooms uses the heat of the moment in a way similar to phone sex. Passions are aroused and given their play. Whether in person, over the phone, by fax, the internet, or by paper letter, the energy of sex between humans causes effects in our body and mind, and perhaps emotions, as we as humans are a compilation of body, mind, emotion, powered on intelligent Spirit. When we write a sexy note to someone whom we are not free to share physical sex with, we are having a sexual experience, nonetheless.
Words are part of the deed.
And, words written or spoken about sexuality can cause sexual reactions in our own and in another's body and emotions.
