Cool, have you two talked about what you expect of each other? Limits? Will you play with others together or separately? Safer Sex?

Sex parties can be a total blast and open new horizons but there are also many traps. Be aware.

The first thing to be sure of is you can say NO! If someone approaches you or her and you do not want them to continue their advances say NO and continue to say no.

Another thing, if you and your GF intend to play together, which is often a good idea for novices as it lowers the potential for jealously, talk privately about who you will play with. Often you'll meet or be approached by someone(s) and they want to play with both of you. Make sure you can privately check with your GF that you both want to continue with them.

Safer Sex! Bring your own supplies! Lube and condoms. Agree between yourselves where your barrier limits are. Do you require barriers for Oral Sex? Gloves for hands? None? Once you set those limits between yourselves stick to them!

Enjoy!
