Essence of theIncubus Lord/Sex God

Gain an ideal form. Said form has demon cosmetics if Incubus Lord, but these are option as a Sex God. Immortality and Youth applies to both cases.

Gain the ability to tame any female creature. This includes ones that you should technically not be able to: Certain Monstergirls and Pokegirls, Succubi Queens and Sex Goddesses, Otherwise untamable or man hating females.

Gain the ability to control how tame a female is. Example. A Hellhound Monstergirls will obey you not matter what, but is she an adoring puppy or a steadfast attack dog? Is the Dominatrix your sex slave now or is she managing the lesser slaves?

All your others abilities can now be recharged or hypercharge by sexual energy collected via fucking. This can also be used for healing and staving off physical needs.

Gain your own private afterlife that no God or any other entity can enter without your permission. Except: Females wanting to submit to you. Said Afterlife starts off thesize of New York City but can grow to the size of Japan. All that you tame will be brought here at death, or by you personally. Amenities will manifest over time.(a month for an apartment complex, a year for a high end mansion, a day for a furnished house.)

All porn logic applies: No refractory period, no incest issues, messiness is togglable, etc.

Can manifest sex toys, even impossible or magical ones, with relative ease.(instantly for dildos, chastity belts, masks etc, but a few hours for a machine that teases, spanks, AND tickles).

Instant access to one lewd (Pokegirl, Queen's Blade, etc) or two ecchi (DxD, New Sister Devil, Heaven's Lost Property, etc) worlds of your choice. A lewd or two more ecchi worlds may be chosen every five years. One year is removed from that for every thousandth orgasm you directly cause (no machines doing it automatically but you can being paddling her, for example).

Gain the ability to shapeshift into a mortal form, and shift your harem girls into human forms if you take them to worlds where they stick out.

Lastly, you also have a Reincarnation + ability. You will lose most of your powers and be reborn with no memory of your past life. However, ALL of your harem will as well and fate will conspire for you all to meet. Only guarantees are that you will have some bedroom talent and be decently hung. Your life will basically be a harem anime with less cockblocking. You also might gain more harem members on these reincarnations. The reincarnation will stop either after the tenth reincarnation or when your harem has doubled.
