I don't fit very well with the idea of masculinity. I'm just a goofy nerd with a gentle personality and the desire to make others happy. I have always wanted to look soft and approachable; I have smooth, rounded facial features, wavy hair, big glasses, and a clean-shaven face. My personality is utterly non-threatening. I love caring for people, I enjoy being silly and whimsical, I'm a bit clumsy and get flustered easily, I wouldn't hurt a fly (unless I had to), and I'm polite to a fault. My paradise is a warm, cozy, quiet safe haven surrounded by cute plushies.
I'm not manly in the slightest, and I love being that way. I'm a total softie through and through, and I purposely align my appearance with my personality. I look gentle because I am gentle.
I have always been treated differently than my male peers. Many people are inexplicably nicer or softer on me even if they barely know me. Female friends have fawned over me, calling me things like "cute," "adorable," and "sweetheart," and expressing a desire to protect me. And I love it. I don't find it offensive or infantilizing at all.
Through extensive introspection, I later figured out that care and nurturing are incredibly attractive to me, and the funny tickle I felt whenever I was shown care and protection by my female friends was actually a subtle tinge of attraction. It's rather curious that my personality and gender expression just happened to develop in such a way to subconsciously solicit that kind of attention.
This is all well and good, but I worry that this makes me categorically unsexy due to my intentional suppression of gendered characteristics and desire to give off pure, wholesome vibes. Could I really be sexually desirable if I'm the kind of person who apologizes to trees for bumping into them? Some women have even teasingly called me a "Christian" or "virgin" because of this perceived innocence, suggesting that some people do indeed associate my personality with sexual restraint or abstinence.
In reality, I absolutely do want a sexual relationship, and I have always imagined myself treating a partner with the same gentle caregiving energy that I myself crave. I don't do "naughty" or "dominant"; I would view a partner's body as something to passionately take care of, not something to tease or conquer.
I would appreciate some outside perspective on this. Thanks!
Added emphasis, as it kind of answers your own question. Being sexy to someone isn't universal. There's certainly things more women tend to find sexy; but it's not an absolute by any means. Think of all the happily married people you have met (assuming you live in a fairly large community). Or even consider all of those in long-term relationships. Not every man in every relationship is super fit and sexy, right? Nor were all the men such when they first met their partner. It is not a requirement! And if you know enough such couples you'll realize appearances of the men in them run the gambit from hot-bod to dad-bod and beyond. And if fact most people in happy relationships are far from the media archetype of "sexy male" as you allude to in your original post.
Not every woman is a lingerie supermodel; not every man is a bodybuilder or Hollywood heartthrob. Yet so many people are able to find relationships where they each find each other sexually desirable. Just randomly scroll through strangers (real poeple) on a social media of your choice and you'll see happy couples with all variety of body types and appearances.
