I would take this to mean that you are into me, very aroused by me and that you feel safe and trust me to let yourself be that way with me! It’s not gross or anything it’s very normal. Personally find it very hot!!!!

Just fyi also. It doesn’t feel good for us (men/penis owners) if you are not lubricated/wet when we try and enter you. So if anything you being extra wet makes it better for us also. In my experience anyway. Like we don’t want sensitive penis rubbing against dry skin. Same principle applies to masturbating or if you are giving a handjob. Some saliva or lube makes it feel a lot better.
