Not swallowing real?

Its rare that I'll finish in her mouth. Like often I'll be getting jerked when I finish or do it myself. But not once have I finished in her mouth and she spit it out. That would be so awkward, and not nice. Like once it's in her mouth it would just make me feel bad for cumming in there in the first place. I simply would discontinue contact with this person as neither would want the other. Unless its just ignorance to which id ask how it would feel for ur bf to need to spit after going down on you?
