Is it normal woman on singles sites

Your thoughts are normal. People who have used dating sites have told me that sane people go on there to find someone and they wind up being turned off and frustrated by the kinds of people they keep running into thus turning them into one of the insane people. It took them years to find someone there and some just gave up. I've been on them too and from my experience they seem to attract a lot of crazy guys and gals. It takes a LOT of patience to wade through it's muddy waters.

I don't say "Cor, great set of tits you have there".

I say "My dear, your cups do overfloweth".

And this is different to the women who are NOT on singles sites how?

Not all women have the same sense of humour, and while every woman I've met likes a laugh, many are not comic geniuses. So, it may be your humour is reaching the wrong audience,,or that the messages you are getting back may not be funny to you. The amount of times on this site alone I've had to point out I was being sarcastic...

There are exceptions to every rule, but most women will show off / favourably present their assets (E.g. Cleavage) in an attempt to make themselves more attractive - and will also find some one who fronts up and says "Cor, great set of tits you have there" crass and vulgar. Don't ask me why this is, I've asked the question for years and have yet to receive a satisfactory answer.

A woman looking for an extramarital affair is looking for someone discrete and able to "read between the lines". It makes sense that they try and remove the fuckwits that are more likely to announce their presence by doing donuts in front of their house.

Conversely, a woman who has a low self esteem may feel the only way she will ever get a man is to "put out". Sex for them is simply the bait on the hook - and they can get irrational when their prospective catch takes the bait and tries to swim away.

Finally, and probably most importantly, is the fact that people tend to attract at their own level. If you have nothing much to offer a woman, the best you will get is a Woman that has nothing much to offer. It's obvious from your question that to you, your average woman is little more than a sperm receptacle, and so guess what you'll find...

Seems you're shit at picking women.

Get to know them first?

I've never used a singles dating site but from conversations with women that have and just generally knowing how the whole dating thing works I'd have to say the OP is simply misunderstanding the supply and demand aspect of the situation.

For example being funny. If you want to get her attention being funny may be a good way to do it. Do you have to do it? No. Will it always work? No. Will she go out of her way to entertain you in return? Probly not. Why should this be? Well supply and demand. She is in short supply but the demand is huge. Its up to the guy to stand out from the crowd that is shouting in her direction. Shes got her pick of more than likely dozens of guys if shes not responding to your attempts at being humorous its a safe bet she didn't think you were funny or someone else was funnier.

I could go through each of these but if you look at the situation from the womans perspective it all should really be quite clear. Oh shes showing cleavage pics? Yes she wants prospective suitors to know what she has. No your not standing out from the crowd by commenting on her boobs. Your another voice in a crowd of voices all saying essentially the same thing. This is boring and not how you create attraction.
