Well for what its worth we use 2 different terms ie. Social meet and play meet.
Social would normally be intial 1:1 contact or when other people are still nervous and unsure whether this is for them. Primarily to sit down, have a drink, chat and gentle (or outrageous) flirt session, either on neutral territory or within someone's home ie. MK meet on 23rd is a social in essence (but if people wish to carry any flirting further that would have to be mutually agreed.)
A Playmeet would be to get more intimate in private, but dependent upon any boundaries agreed and set beforehand. ie. lots dont swop and fuck on first play, prefer to engage in horny foreplay and revert to own partner for 'completion'.
Hope this makes some sense? It seems to work ok for us 2.
Take care, have fun...
