Thanks for all the advice so far folks.

Let me just state for the record that I do not have any intention of cheating on my girlfriend in any way. While I do wish that we had more sex and more interesting sex, I feel a deep emotional connection to her that I would not jeopardize for anything. I have absolutely no intention of doing anything behind her back at all and I would want her either present or completely complicit in anything that occurred.

Her bestie might want to jump my bones but she has no shot unless my girlfriend is very much ok with it. I'm all for swinging and 3somes but I would never push the woman I love into something she wasn't comfortable with.

That said, I would be more than comfortable sharing my girlfriend with another man, assuming she was comfortable with it herself. I love sex and nothing turns me on more than seeing a woman enjoy herself sexually and if this would help her achieve more pleasure I'd be all for it.

We do have multiple toys but for the most part my girlfriend enjoys the feel of me personally, according to her I am some kind of sexual dynamo and her constant bragging about it may be what attracted her bestie to me/us in the first place.

Please keep in mind that anytime the bestie brings up sex and swinging, it's always in the presence of both me and my girlfriend. She almost never mentions sex when we have the rare few moments alone.
