Advice on a foursome?

My b/f and I have a 4sum planned for june , were good friends with the other couple and we all like eachother(strictly sexual)and were all very open about these things...theres no chance of jealousy or falling in love.ect.ect.everyone is comfterable with it and such...but I was wondering what other people thought of 4sums...and if anyones had them id like to hear about your experience.

Erm... I really think that 16 is too young to be thinking about foursomes. I know you say there's no commitment and it's strictly sexual, but don't you think it's a bit of a worry, that your sexual life has ALREADY gotten so dull that it needs to be spiced up to such an extreme. This is the sort of thing sad couples in their late 40s do, to try and bring back the thrill. However if for what ever reason you do decide to go though with it, at least have the sense to use a condom...or two.

ofcoarse im not going to risk my health for fun...and I turn 17 in june...anyways its not to add spice our sexlife rocks...but alas I am a nympho and weve already done a 3sum...it was so fun...but now I want to try this.I was just wondering wheather anyone else has...and how exactly it works out.

At your age, your probably going to pretty much be alone with this type of situation.
*A nymphomaniac is a woman who literally needs sex so badly that it interferes with her daily activities; she will go out of her way to get sex in innapropriate places and from innapropriate sources. She will not be able to do normal things in her day, like washing dishes, going to work, driving a car, because the need for sex interferes.
I highly doubt your a nympho.

multitask

ud be surprised.
but its not that serious to where I cant do anything else...but I do need it multiple times a day...or I cant concentrate on anything

I had threesome, and it was a big fun. You need good sense of humor and ability to give yourself.
