Nope. They get a bigger dick and more sexual stamina. If they have any issue restricting sex such as frailty or old age, that issue is healed. And if the mamono lives under conditions that humans can't survive the incubus gains a resistance to those conditions. A man married to a Salamander would be able to withstand extreme heat for instance. They also gain the ability to survive off of nothing but sex and produce more spirit energy to feed their waifu. But they don't get anything else. No super strength, no speed boost, no becoming bullet proof, no being able to seduce women like the mythical incubus. It's just a way to adapt to being with a mamono.
