I know this is a serious question and deserves a serious answer but my lack of maturity requires that I ask, is this considered neckrophillia?

I'm not partial to the neck in particular, but I have asked men I've dated to not wear cologne so I could smell their scent. It's make or break for me.

There's something about complimentarity of immune systems. It's genetically linked, and signalled instinctively via scent. When a potential procreative mate (dunno about homosexual pairings; suspect it's similar) has an immune system that meshes well with yours, they'll smell irresistible. The idea is that nature wants you to boink the person whose DNA will combine with yours to produce the fittest possible offspring.

That's not necessarily someone whose DNA and/or immune system is like yours, either: due to inheritance of recessive traits, it's more likely that someone with different genetic traits is going to be nature's idea of a good mate for you.

There's something very primal about being able to distingquish your mate's distictive smell when she/he is around.

Can't say I specifically sniff necks but I do like overwhelming the senses with extreme physical closeness; touch, smell and sound. It really feels like an altered state.

I'll be sure to wash my neck and behind my ears from now on. ?...just in case...

It's entirely pheremonally based, and I know it. Sorry, if there's no chemistry, nothing will ever happen. Decent chemistry can make up for a guy not meeting my personal tastes. I prefer small and dark, think Mediterranean... and I'm still dating a large white Russian guy, because the pheremones and personality are compatible. I think he's pleasantly ugly, but I'd never tell him that.

If they don't pass the sniff test then it's a dead end----

I didn’t realize this was a thing, however since you posted I feel the urge to sniff a neck.

If a potential partner is comfortable enough to let me get that close, then, of course, I am going to drink in the pheromones. It isn't necessarily an overtly obvious sniffing of the neck, but a deep inhale followed by a sigh of contentment while in a nice embrace handles all of that, nicely, and without awkwardness.

Sniff lick bite kiss mmm necks are great especially ones that smell good. it turns me on a lot, especialy having my neck sniffed and kisses and bitten.

I do but not like "SNIIIIIIIIIIFFFFFFFF- ahhhhh"

Ok who tagged this kinky? rofl

A hug will do it

Scent is important to my experience. I sniff all. I usually want sex BEFORE she showers

The long slow sniff along someone neck is an erotic gesture, so, yes I have been known to do this.

I don’t specifically sniff necks, but I do notice a lady’s scent when she’s nearby. To me, being aware of how you smell is a just part of being groomed

I never thought about it, but I do love the smell of the necks of my loved ones. Not sure if it's something I would do as a test, but maybe each has a smell I have learned to love because of my feelings toward that person. (babies, intimate partners, etc.) I think it's natural to breathe in the scent of loved ones as a pleasurable thing. I suppose if I didn't like the smell of someone, I wouldn't get close enough to find out what their neck smelled like.

But, I'm not quite as picky. Pheromones are definitely important, but it takes more than that to make a "zing", or break one!

Yes, I do it, but had not given it thought prior to this question. It is not a deal breaker, but some ladies are delicious,

I don't think I do it intentionally but, I do know that the smell has an affect! (Hopefully not making something curl though. That would not be a preferred outcome.)

If you know,
How many necks have you sniffed?
How many resulted in you having positive reaction?
How many resulted in a committed relationship?

I'm not a sniffer, but I've been known to nibble a bit

I'm a human and I sniff necks.

Only female necks mind you! A woman with a long neck is a feature to me!
