Straight male here, I’m not who you asked but here’s some data. I wear a small silver chain, it was given to me as a teenager and I very rarely take it off. Basically every woman I’ve slept with has grabbed it to pull me down to kiss me.

No, but I don’t really care either. It’s quite neutral. You do you.

Not particularly, I’m indifferent to necklaces. Can’t really judge, I have both a church necklace and a waistlet.

Hot. Also depends on the body shape, it’s like a welcome sign down to a good time if he’s cut nice. A happy trail (hair that leads from the bellybutton to navel) on a dad bod also fits the aesthetic.

Yea I think they look sexy

If you think you look better with it on, then chances are you do look better with it on, because you’ll feel hotter and more confident! So wear it :)

Yes. It’s like the male version of cleavage.

If you want to wear a necklace or - anything - you should just do it.
I know it’s hard to believe when you are still young, but when you are wearing somersetting YOU like, it will make you happy. And a happy person is attractive.
It’s just a plus that any chosen accessory will attract people who have the same taste :)

It worked for this guy:

I know of at least one person who specifically has a big thing for gold necklaces

It’s really dependable on the person. Like how some guys can pull off a hat and others can’t. Everything from physical characteristics to confidence and maturity effect that. If you like how you look that’s all that matters. Rock the pendant and give someone a reason to see the better view 😉

If I find the particular body in question attractive, then jewelry will serve to enhance that experience for me. It accentuates the shapes.

Yes! I wish more men felt comfortable wearing jewelry. I like the addition of jewelry to any body!

yes

One of the purposes of jewelry is to enhance looks. It can serve to draw attention to specific features.

Now, there is a disclaimer needed here. I’m hetero. So I have no sexual attraction to the male form. However, I’ve dabbled in multiple forms of art, and used to jang around weight rooms with some bodybuilders among the mix. So you either learn to appreciate the male form or you GTFO of both of those PDQ.

Necklaces can very much enhance a chest/torso. It’s all about the kind of necklace. Understated is usually best. A single pendant, with the chain/string/whatever being are the right length is going to pull the eyes to the center of the chest most of the time. This can be a very good thing. You adjust the length to match where you think that extra attention is going to give the best visual, and you’ve succeeded in jewelry.

Even a very fine chain can also give a visual break. Depending on the hair situation, chests can actually be boring to look at. A lot of hair, and it’s a visual sameness just like a total shave is. You need light and shadows, variances in tone. If you don’t have that naturally, you can supply it with jewelry (works with piercings too, btw). I’m a fucking sasquatch, and there’s more visual interest when I’m wearing even something utilitarian (a keychain sized flashlight is damn handy on a chain) rather than jewelry.

So I’m not surprised you prefer the looks when wearing your necklace. Makes total sense.

Now, sexy is as sexy does. If someone is into necklaces as a paraphilia, or just as a mild nicety, you can’t really judge whether the jewelry makes you look better or not. Most people I’ve ever heard talk about male jewelry at all leaned towards a little being enough, rather than any specific type.

But, yeah, I’ve seen enough dudes shirtless to have the opinion that a tasteful piece hanging somewhere on the sternum is sexier than without, most of the time. Doesn’t turn me on, but that’s not necessary to have an opinion about sexiness per se.
