Eat it until she cums or don’t eat it at all.
That’s the only way I eat
While I appreciate where this is coming from, and it’s certainly what I try to do, it may not be the healthiest attitude. If you go into it thinking, “if this doesn’t end with first class tickets to orgasm city, it’s a failed sexual encounter,” then you’re just setting yourself up for disappointment. There are a multitude of reasons why either partner (of either gender) may not orgasm on any given day. If you just communicate with your partner and focus on enjoying the experience, rather than focusing on the giant looming thought of “everyone has to orgasm always,” then you will have a much better time. Not cumming isn’t (always) bad.
Just my two cents. Sex positive stuff or whatever.
Now get back out there and eat it.
