Dr. Mallard's Diary: Entry 9

On sexual relations with ghosts

It is quite possible to have relations with a ghost, however it is not in the way that you think. Ghosts do not have bodies. By definition, they are the things they possess (i.e . houses and the objects within). Their manifestation or their spiritual projection does not have any physical substance and is by nature an illusion.  And so how is one to remedy this fact?
The simple answer is possession. Now this is by and large a risky procedure as there is no guarantee that the ghost will release you afterwards. A ghost after all is the essence of memory-the desire to cling to life. Therefore, it would be a risk  to your own personal safety. It's a very risky form of CNC if you think about it. Now, I'm not one to kink shame- do what thou wilt- however, I would recommend that you have some form of protection, like a cool priest or a willing exorcist to remove the spirit afterwards. Consent is in fact key here as a ghost cannot possess you without permission, and so placing proper contracts and warding should also help.
In this case, the ghost is now able to stimulate you and itself via masturbation. You can also have someone else be possessed by the spirit, but honestly it's just like screwing another person at that point. There's no fun in that. The pleasure is in the invasion and the binding of wills and also a connection with the otherworldly. Quite literally. 
Enjoy and and don't forget to use protection. Seriously, ghosts are a pain in the ass...and not in the fun way.
