It was established early on that neither of us date multiple people at the same time and that we will be/are exclusive.
As I said, a distinction is made occasionally when we talk. Talk to your boyfriend to get things squared away!!!
Do you want the other person to have sex with other people while they have sex with you?
The two of you may also choose be exclusive out of respect for one another and safety. You may choose to see them exclusively to see how things progress without without the distraction of dating anyone else.
Who cares what other people do or how they label things ? but I could see how someone might distinguish them.
Is the purpose for your question to clarify your position in your relationship ? I would guess someone who said "we are dating exclusively" are trying to leave a backdoor for themselves but still keep you tied up just for the mean time till they know for sure about you. Dating exclusively means you go out on dates with only one person at a time, presumably for as long as it takes to figure out whether or not you can stand the person enough to be in a relationship.
The exclusivity only means that when you ask for a date and the answer is ``I'm busy that night,'' that ``I'm busy that night'' doesn't mean ``I'm busy boinking someone else that night.''That's news to me.
I want to be exclusive when dating someone and adding intercourse to the mix, and I would prefer that she does the same........does not necessarily make us the dreaded girlfriend/boyfriend thing, it just means that we are enjoying each other to the point of having sex and that we care enough for each other and ourselves to do that exclusively.
To place labels on things like this just is a turn off to me.
Bottom line, with reference to your area of interest OP, never assume anything each of you say means the same thing, until you verify that it does.
There has never been any such thing as a truly authoritative source for the meanings of any word.
