When it comes to being online, or in person, it’s always important to be safe and take precautions. What you are up to and what you are doing are going to determine what you need to do but there are a few things that you should always consider.

Meet Somewhere Public
A coffee shop, a restaurant, a park, whatever works. You should always meet somewhere that is public which will prevent the other person from doing something crazy (if things go that way).
Take Your Own Transportation
Never let the other person pick you up or drive you around. If you are driving home after and you feel like you are being followed, do not go home, go somewhere public or a police station if you are scared.
Listen to Your Gut
If you meet someone, or they suggest something that you are not comfortable with them, do not be afraid to say no. Worst comes to worse, they decide that they do not want anything to do with you, and really, do you want to be with someone like that?
Do’s and Don’ts
Are there certain things that you refuse to do or that you love to do? Let your partner know. It’s always best to tell them before you hook up so that you can avoid any discomfort and allow you to see if the two of you are compatible.
Protection
If this is someone that you are potentially going to be getting intimate with, discuss birth control. Many men do not like condoms but they are willing to use them if it is the difference between sex or not. Do not let a partner guilt you into not using them as they enjoy the sensations without or they perform better without. If things go well, there is lots of time for that down the road.
No matter, is a good idea to let someone know where you are going to be and when you expect to be home. They don’t need 100% specifics but the more they know, the better, just in case. There has been a time or two that I have sent a friend the information about where I am going, who I am meeting, and their contact information. You just never know (but hope you never need to use the information provided!)
