discharge during sex

My boyfriend has managed to coax a female ejaculation from me before, he claims it was a gush of clear liquid that made a wet spot on the carpet (I was bent over the edge of the bed). Today I've noticed that I was having mild discharge all day, which I usually interpret as a hint to ovulation. Since there's little of it in my underwear, I can only say that it seemed to be clear/pale milky white. Didn't smell "off" or like urine, so I've never been alarmed (kind of like my natural wetness, I think...)

We had sex in the missionary and it felt intense. When I came he said there was a gush of wetness, and we looked down to see the same milky stuff all over his base. There was so much of it that he thought he broke the condom and came too, but we've checked. It was more opaque and apparently he saw it "explode" out of me like the time he stimulated my ejaculation.

What was the white stuff??? We see something similar all the time when we have sex, but it's very little in amount and usually gets caught in the wrinkles of the condom at his tip. Never seen this much (if it were the same thing)!!
