We LOVE Creampies; What are YOUR Thoughts on Cream

My girlfriend and I love, love, love creampies. In fact, it's really the only way I want to cum. She has told me on numerous occasions that she wants to swallow my load, which would've made for an incredibly fortunate situation in my younger days. As it stands now, creaming her pussy is the be-all, end-all for me. I imagine that's a biological thing, but there's nothing more exciting for me than cumming deep within her crotch. What are your thoughts/experiences regarding creampies, oral creampies, and other forms of "happy endings"?
