I've used that site, but no longer. It was a complete waste of time for me.
After having a previous relationship with a rich man I thought it might be an idea to give it a go. From previous experience I seemed to equate success with togetherness - not as a human bank account. Wasn't looking for someone to give me money at the time, yet after each date I was handed a small amount of money as a thank you.
I met several wealthy men from there.
One is currently stalking me from afar with regular e-mails telling that he fell in love with me after one dinner. He deposits money into a bank account on a regular basis even though I've told him to stop, and I haven't touched that money with the intentions of withdrawing it and putting it through his letter box next time I'm in the area.
Another lives abroad but spends half his time in the UK for business and to see his children. I did spend one night with him where he constantly begged me for anal sex and I'm just like, "No, get a grip or a hooker" lol. He gave me ?40 for my taxi fare home.
And then there's the white man. He wears white shoes, white jackets, drives a white car, hates that I didn't wear white on our date. He wanted me to lie about my age, making me several years older to be the same age his ex wife was and wanted me to dress like his ex wife. That was the last straw and I deactivated my profile... After taking the ?400 that he thrust into my hand the last time I saw him.
Needless to say I no longer think that successful men are very together emotionally. And on that site they seem to either be looking for free sex or someone they can buy. Which is fair enough, but that's not what I was looking for after being in a relationship where I had my own money and we both had the disposable income where if on a whim we felt like catching a flight to London so that we could see an exhibition or a show we did.
At the same time I was on SD, I also registered on POF... seems to me just a bunch of people looking for a string of one night stands, all at no cost to them. Although I met someone semi-famous through POF who is an absolute gentleman, and we still meet up to go for coffee or the theatre occasionally.
So after all that rambling, just my personal opinion of dating sites is that they're not all that good to use for work.... unless your overnight rate is ?300-400.
