Granted. I just finished reading a few of Cool-kyou Shinja's works, so I got a pretty definite idea on what kind of life you're gonna get

Good news is that you are very short, one could even politely say "petite", the kind of young man that MILFs could gobble up (no voro). All women, regardless of personal tastes, will find you adorable and will, at the bare minimum, coo and attempt to headpat you to an unhealthy degree. They will also instinctively know about your needs, and will move to satisfy them... mostly. More on that later. Motherly women will be affected significantly more.
Just like you asked, you have an immortal and unaging body, and I'm also adding invulnerability for free; you could be thrown into the Sun and still come out fine. Pretty much the only way you can die is if you desire such, and even then it would only work if you are really, really, really sure. By the way, the invulnerability also comes with an immunity against insanity.

Now let's move on to the drawbacks. You might have godly CHA and COS, but that comes at the expense of... well, most of everything else. You tend to be a bit clumsy, forgetful and easily distractible, although these latter flaws are just a smidge above "adorable quirk" level. They will still inconvenience your life, but not too much.
The biggest problem is physical strength: you are incredibly weak, to the point that even a child could easily restrain you. Against a group of women who want to dote on you? You got no chance, no hope, and no freedom. Sure, all your needs will be taken care of... but your wants are a different story. If a woman wants to make you wear cutesy clothes, she will. If she wants to use you as a teddy bear while she sleeps, she will - and if she ends up rolling over you, forget about getting out. If she thinks that you need to use the bathroom, she will follow you there - you know, to make sure her little man doesn't have any problem. And also to squeee out a fee orgasms.
