Yes. At first it was only online, a few times in person as well but rarely in my face. I do notice they stare hard though, and a few of them have actually said something.
My DB is white so it's definitely flattering but it caught me off guard the other day. I've been working out and eating healthier, dropped a few pounds, etc. and I was craving something non healthy so I went to grab a coney dog. I've seen this guy before, tall, handsome, blonde, with blue eyes but this day I just wanted to enjoy my dog and I wasn't focusing on anything but. I'd just come from the gym too.
He comes over to me (I was sitting at the counter) and asks me if I was all set to pay. Then he lowers his voice a little and asks "Are you single?" Silly me I said "Yes" and then, "No." I was so caught off guard it didn't register. My poor DB at military boot camp at the time had a girl forgetting she was in a relationship for a split second
I love my DB but mannnn, if I weren't taken I'd be all up in that ***. He was foinnne.
ETA: To answer the question, I think that it really does depend on the individual who's doing the approaching. The "look" of the lady he's approaching, location etc. Just having moved from NOVA myself it's more socially acceptable. DC,MD,VA is full of interracial couples with the majority of the white men being professionals and so are the black women. (not saying that women who don't look professional don't get picked up)
When I was younger I never really got hit on. I had a few black bfs here or there but more whites as I got older (I'm 25). Brothers rarely hit on me in NOVA but when I moved back to the midwest black men finally picked up on a girl. To be honest, I think it's all in my appearance. I tend to walk with a strut, confident, look like I'm in a hurry too, and stuck up/prissy, or spoiled. I know this because both male and female classmates have told me they didn't know I was so cool until after I spoke
A few black men who've approached me at my college always tell me they had noticed me but were afraid to say anything because I looked like I didn't want anything to do with them. However, I'm one of the most outgoing and friendliest, I just happen to look like a sexy, cold hard *****.
In fact, when I was enjoying my dog I believe I may have just looked approachable. Funny thing is, that coney hot dog place feels/looks segregated then a mother ****er. All the old white heads all go there and when a sister walks through the door they stare hard. I always feel like an outcast in there though I grew up in a predominately white community so when that guy hit on me I was very surprised.
There is definitely a stigma, but I don't think it's what we all assume (black women being dominant/hard). Most white men in particular who are interested in black women have always assumed that we were just not interested in them. And believe me, there are plenty who are and visa versa. Many of them say that they've been shot down publicly by black women and how they only date brothas. This is usually the main cause of them asking you if you date white men.
I once dated an Asian, he approached but he was a "tiny" little bugger if you catch my drift
I remember in DC on the train when I first started wearing lace fronts this Hispanic guy just started hitting on me in Spanish, asking me what I was when I told him black he apologized assuming that I was part Spanish because my hair was pretty.
Another Spanish guy on another train was just plane disgusting and crude I had to move away before I cursed him out. I did get hit on by a few Middle Easterns in NOVA but found them to be the most crude. One guy had two wives in his country and tried to make me the 3rd. No Sir.
erplexed
Get the **** out. The non-black dude looked shell shocked at the outburst.
even wear one in my nose. when i go to the club/bar i wear them so big they almost sit on my shoulders.
. I don't mean anything superficial like clothes or hairstyles, but I find in general black men are more into their bodies. Every black guy or well almost every that I've dated has had a beautiful athletic body. White guys, not so much, and their hips... oh em gee...
Toting his chubby self around makes men, esp white men take notice
