Tasting sweet

Hi ladies! So my fiance came home after being away for 2 months (he's in the marines) and of course we having mind blowing sex. He went down on me and when he finished, he told me how I tasted amazing, literally like candy. I thought it could've been the lotion I put on my body, cuz I put some on my butt. I got the bottle and had him smell it but he said it's not it. I have no clue what it could be seeing as I didn't do anything differently. Any ideas on what it could be so I make sure it happens again???
