Hi James,
Welcome to the wonderful world of online dating. Where the people are lonely and some kinda horny. I have been on here for a couple of weeks and in that time I have learned a few things. So all ears attention while I pass on these pearls of wisdom.....LOL I'm sorry I can never keep a straight face with that line.
So seriously here is what I suggest.
1) It's OK to have no pic on your profile page- it helps weed out those out there looking for sex. Plus anyone who contacts you will have an honest interest in you based on what you have provided (so make it good).
2) Of those who have an interest in you....like 70% will be older...like much older...That's great if your looking for a sugar daddy or maybe you inherit some junk when they pass.
3) Putting up a pic of yourself will draw more attention to your profile, even if it is hideous! Trust me!
4) Do be active in your time here. Seek out others. Don't just wait for them to contact you.
5) Have Fun! Chat with as many peeps as possible. You can usually tell if either party is interested based on a live chat.
Good Luck!
