use of tongues in interracial kissing

[cuckolded wimp]

I am wondering what people interpret, when they are kissing and the partner inserts their tongue into their mouth. Is it a sign/signal for something else? Does it mean someone is showing their domination/ submission? And is there a time to do tongues ( first kiss??). Just throwing up another thread that may have a discussion element, "which shouldn't be controversial".

I almost instantly get an erection when a woman (even my wife after 19 years) kisses me and sticks her tongue into my mouth. My almost, immediate reaction (besides sucking on her tongue) is to take my hand and start rubbing her clit from outside her panties until I feel that familiar wetness. Then, some earlobe sucking, and neck kissing, and my prick is as hard as a 10- penny nail, and just about the same size ...
