Fluid getting out after fingering?

Bros, please don't be too hard on me. I've discovered the great pleasure of fingering whilst masturbating and it's been cool and all. Only, about 10mn after finishing, I start farting a bit, which isn't a problem alone, but a little fluid comes out sometimes. It doesn't smell anything more than my arse. Does that happen to you? Is it "normal"?I never had a penis or anything bigger than one finger in here so I wouldn't know if that also happens when having sex.
