Hello, my name is Professor Harry P. Enis but my friends call me "Hap". The majority of my life has been dedicated to the study of Genitology, particularly the interactions between the male fleshy appendage commonly referred to as the penis, and the exquisitely designed, awe inspiring female orifice surrounded by labial folds known as the vagina. After many years of extensive research and exhaustive experimentation, the evidence would seem to indicate that by strategically inserting the former into the latter, one can create heightened sensations of extreme pleasure and euphoria, resulting in an explosive discharge of seminal fluid and vaginal secretions. However, the data is not all in. Therefore, as a personal sacrifice, I am donating my own fleshy appendage in the interest of science and need volunteers. Anyone possessing a vagina is strongly encouraged to contact our organization, the Founders Of Respected National Institutes Concerning Adult Training Exercises or our University chapter, Campus Organization to Prepare Undergraduates for Life And The Essentials. All volunteers will be treated with the utmost dignity and respect in what promises to be a very fulfilling experience. All of us here at F.O.R.N.I.C.A.T.E. and C.O.P.U.L.A.T.E. are firmly committed to understanding every facet of this phenomenon and will work tirelessly until everyone is fully satisfied with the results. Thank you for your consideration.

P.S. Pics of said vaginas and/or their owners are welcome but not mandatory.

Ok, that was for fun. Now for the REAL ad:
I am married but, for various reasons, I have no plans on changing that any time soon. Therefore, I am extremely careful, clean, and discreet. I am also a very thoughtful, considerate man with a creative sense of humor. I am simply looking for a safe and sane, intelligent woman or couple who want to have some fun sexy times without any other drama. If this sounds appealing to you, then please send a message and let's talk.

Non-monogamists break with the societal tradition of having just one partner at a time. They will prefer to be in an open relationship. They can be called polyamorous. They don’t see sex or kink as something to keep between themselves and just one other person. They can have several partners at once, these can be just for play or more serious relationships. Every non-monogamist will have different approaches to non-monogamy. Polyamorists will have, or look to be in, more than one relationship. These will be more than play and sex, and involve a romantic and/or intimate aspect. Swingers may be married or in a committed relationship with one person but they will indulge in kink or sexual play with other people too. Swingers can be single, it’s not all about wife-swapping. Anyone not in a monogamous relationship can be referred as polyamorous. Non-monogamists can indulge in all kinds of fetishes and kink play. They can be Dominant, submissive or switch if they’re into BDSM. They will rarely be slaves as devotion to one Master or Mistress doesn’t come easy to them. However, they might work well in a relationship with multiple slaves and one or more Dominant partner.
