No, you're not the only one. Part of the satisfaction in this sort of fantasy involves being in a personal relationship with the woman of your dreams. And part of being the woman of your dreams means she has fetishized physical attributes beyond the realm of the impossible, ones that would make it impossible for her to blend into normal society.
Which raises the question, just how did you of all people get into this relationship in the first place? Because surely such a woman would either be a total outcast, or have much better prospects and never give you a second glance! Simple, your lady didn't always have the ability to grow superhuman muscles that are totally impractical for day-to-day life; that came after you already got to develop your relationship with her on a deep and genuine level, in a way that calls back all those silly sentimental boy-meets-girl stories.
As for why the repeatable hulkout ability, instead of a one-way transformative process, well, it's great to have your cake and eat it too. All the thrills of access to a goddess body, without having to give up your normal life. Be able to hang with the normies, and also have the spice of She-Hulk! Plus, all the joys of watching her grow, repeated anew an unlimited number of times!
Or at least, that was my particular thought process about this!
