Hey! Glad you are entering the wonderful world of dating - its lots of fun and internet daitng is just one wayof doing it.
I have used Match and found that there were sooooooo many men that there were enough that I liked the look of. But, yes it costs money.
My top tip would be to relax and have fun. If you think if it as a great way to meet people, get out of the house and find out a bit more about what you do and don't want in a relationship, then you'll definately get that, and you might even meet someone special as a bonus!
If you can read, Sarah Beeny's guide to dating. I found it at my local library and it was very funny and is a kind of irrelevant guide to dating and includes stuff on internet dating.
Another tip I found useful - make your profile appeal to your ideal man, not lots of unsuitable men. For example, I like quite a few 'blokish' activities like caving and riding a motorbike which might put off some men. I considered not putting them in, but then thought, well, my ideal man would accept me as I am, so if they arn't interested, that's fine. There are plenty of fish in the sea and all that!!!
Let us all know how you get on.
