Why does my "stuff" taste sweet?

So I’m going to try and keep this as non-graphic as possible… bear with me…

Last night I’m with my “g/f” and we’re being “intimate”... One things leads to another and she ends up “going down to 3rd base” with me…. well towards the “end” she lets me finish in her “mouth”...... Then shortly later she told me that my “stuff” tasted VERY sweet….. Moreso than other “stuff” she has tasted in the past.

So I thought about it, and I know that eating lots of fruit will have that effect on “stuff.” BUT, I don’t really eat all that much fruit. Then it occurred to me that I drink a LOT of mountain dew, which contains a “boatload” of sugar. Do you guys think that that excess of sugar could be the cause of the “sweet tasting stuff?”
