Such a loaded question. I have no idea, I never kept track, really. I know it's very very high due to past stuff I did, and when I tried to make a guess because the at the time boyfriend wanted to know, he dumped me the next day because he thought it was "too much".
Now I don't even answer with a guess, I just say "I don't know".
As for partners, I'm currently seeing 3, plus some casual dates here and there, and it's getting to the limit in terms of time to dedicate to each and to myself. The good thing is that 2 of the 3 have other relationships as well, so they also don't have too much time and it balances out ok. I can't imagine adding another partner, although I'd be open to the possibility if it happens.
