Many men really enjoy it when their gf or wife swallows their cum and may feel slightly rejected if that same cum is spit out. If we as men think it's okay for women to swallow, what harm is there ...

You'll have to find somewhere else to "dump your load". My wife is not a dumpster!

It might be a condition called Misophonia. It's real and unfortunate.

If I were more flexible, I'd definitely try to drink from my own cock...i agree that the mix of juices along with the increased intimacy with my wife is really erotic and wonderful!
