I Am A Male. I Am Gay, Sometimes While Fingering

I am a male. I am gay, sometimes while fingering my anus, clear vaginal like fluid like come out. it is sticky sometimes, and it can smell funny, or have no smell at all, sometimes it has a weirder yellowish jelly like substance. I don't know what it is? I know this may not sound like a normal question to get asked, but it is quite embarrasing for me to just ask someone about in person.
