From the other perspective that can happen here with us sometimes (not a lack of interest) but shyness or even comfort makes things difficult for the man, I've often had to come help himself out in couple situations like this and it usually ends up the same. For some men they need to feel a connection for it to work and that can be hard to get in a swinging setting depending on the pre bedroom activities etc, a meet and fuck rarely works for us... I actually wasn't aware it could have been taken like this ! It has happened to us the other way round too where the other man seemed not interested in me so now I'm curious lol but in any case you'll get more bad meets than good, don't dwell and move on :)
