I think your profile sounds fine, info. (although I'd be put off by the mention of being into cars, but have to stress- that's just me! Don't change on my account!). But it sounds like you're not messaging many people??
I posted on the last thread that I was downhearted because I'd sent five- five! messages, and only received one reply, and that a brush off (I've been on OKC for about 6 weeks, by the way). They were all carefully crafted and personalised, sent to men I thought were interesting (sulks).
I have received various other messages, but they've all been of the "How r u?" variety....I did answer one, out of curiosity (and because his photo looked nice) but it was pretty painful: "Hi, I see there's not much on your profile- like to tell me about yourself?" "What do u want to know?" "Well....let's start with what have you been up to today?" "Working". At which point I bailed....
I did get messaged by, and go on a date with, one man- thought he was OK but not really right for me.....when he realised I didn't want to see him again he sent me a horrible message calling me a "fucking bitch", among other pleasantries. Nice!!
My profile is really quite long, rambling and, er, "quirky".....but then, that's the kind of profile I like to see in blokes! In a way, it's difficult seeing others refer to this whole thing as a numbers game, because I live rurally, and am an intellectual, artistic type looking for similar, so that's the potential numbers slashed. Mind you, when I was last on OKC I ended up getting together with the first person I went on a date with, and we went on to have DS2 together (then we split up, but anyhoo. Onwards and upwards).
Having said all this, I DID receive an answer to one of my messages some days ago! It's someone who checks OKC very rarely (he said). He does sound interesting, and we're due to meet next Saturday. It's weird having to wait so long though (we both have various commitments)- we have been texting quite a lot, but I don't know how much investment I want to put into constant texting before we've met. I'd be quite happy not to text him for a few days, but hope he doesn't go cold or get offended by that....
