...we have our brains laced with nano-neural networks (40 years?) we will eventually be able to experience completely virtual body sensation, so we can have equal or better quality sex with partners in virtual reality, or with combinations of virtual reality and material reality; two real people in a virtual space, a virtual partner in a real space, two real and one virtual person in a semi-real space, whatever. Nano-neural networks and new psychophamraceuticals will also allow us to modify and enhance sexual and emotional experience, to have orgasms as long and hard as we like, or no orgasms, or to have an experience of cosmic love and oneness instead of an orgasm, experienced as a bolt of tingles trough every inch of our body.
