I 23F am considering playing with a couple (late 20s and early 30s)

Their profile presents it as them looking for a unicorn but as I began speaking with the boyfriend who runs the account, it seemed like it would be just us playing, as they’re still undecided on a threesome situation.

And I would be fine playing with just the boyfriend aside from the fact that he said they’ve only been together for less than a month.

Am I weird for feeling uneasy about that? I guess it’s not my concern but I don’t know. I really prefer playing with older more mature and preferably married couples. Especially for 1-1s. The few times i’ve played with younger and less established couples it’s ended in a bit of drama and hurt feelings.
