As long as I can stay contracted to a single mortal, whom I can keep ageless via shapeshifting, I don't have to "liberate" anyone. Just them once to be on the safe side and I'm good. Other than the ability to summon me, they don't have any real power over me, but I still want to keep on the good side of whoever has my contract so they won't end it. I can provide services in the form of the aforementioned age shifting or any other variety of form sculpting, so few people would be spiteful enough to terminate me unless I really did something to piss them off.
I'm a shapeshifter, so I can freely shift my form in any number of ways and maintain immortality for myself without having to buy it separately. I have enough +health to be immune to disease (or at least to be able to recover from any disease naturally), which is essential for maintaining an immortal life. Shapeshifting others is powered by having sex, either with them or someone else, whichever I prefer, but such things are simple enough for a shapeshifter.
The combination of fertility effects make me functionally infertile. I can only create spawn, and only through one odd and unlikely pregnancy type of my choice. I choose for that to be inflicted testicular pregnancy. The only way any pregnancy is going to happen is if I shapeshift a cock, insert it into another man's cock and then cum. That's not a fetish, it's just something that fits the requirements that I'm extremely unlikely to ever do. The whole thing nets me an extra 2 points in addition to making sex safe.
