defining moments

a lot of people believe in the adage "tell me who your friends are and i'll tell you who you are" but then again, consider these moments:

saw my partner's couple friends in a bath house, well, much as it was awkward, they kinda know that the partner has allowed me to play around so i was able to manage through the sticky situation; ut then again it gets a bit more awkward. friend one starts to talk and star some light chit chat about how i was doing withmy workouts and the progress ive done. then it happened, as we talk about gym and the gains ive gotten, he starts to touch me--and starts to hit on me. ohhhh-kaaayyyy...then his partner (who also happens to be my partner's friend) joins us and doesnt mind that his partner flirts with me annnnddddd....he starts to join in the flirting...a few more touching and ive got an invite for a threesome.....yup ive got an invite for a threesome with partner's friends.

lately, ive been talking with another of partner's friend. we get into the conversation about gym. at first it seemed as if he wanted to get tips or a few pointers or maybe just share notes; then bam! he tells me he wants to sleep with me.

now, these guys aren't bad looking. at all. they're quite lookers in their own right, and the men behind these looks just make the package a lot more inviting. im not exactly one to be moral especially when it comes to sex (heck what right do i have?!)but somehow there's something iffy about sleeping with partner's friends. it feels like true-blue backstabbing.

am i being...? y'know? what would u do?
