I agree with Watch on this, although I don't agree with everything she does.
Every single dating site tells you to keep safe. DO NOT let them pick you up from home, PLEASE. You meet in a public place and you make you own way there and back. You've never met these men and they might be perfectly fine, most are, but you are taking a huge risk. Dating someone you have met before and have a mutual attraction to is totally different. You both know you want to kiss, cuddle even shag, you've met before!
I have had lots of experience and these are my rules:-
Rule 1 As above
Rule 2 Drive, if possible to the first meeting, don't let alcohol cloud your judgement, keep the beer goggles, firmly off
Rule 3 Don't take them home with you on the first date, even if you want to shag their arse off.
Rule 4 See above, don't shag on first meeting.
Rule 5 Reflect on the date and let them get back to you and if you want to see them again, knowing you both want more then the rules are relaxed but still be on your guard.
If they guy is worth it then he won't mind you sticking to the rules and I would be a bit suspicious if a man thought it was OK for him to pick you up. He might think he is in already.
