KTF40, do you think it is your technique that is getting her to orgasm regularly, or her comfort level with you, or both?
Both, but I'd say technique is a little more important. For her, I need to lick her clit at a consistent pace (typically a slower pace) in an up down motion, using slightly more pressure when I lick upward, and completely stay focused on that area. She's never had an orgasm from oral using any technique other than that, with me at least. At the same time though, comfort level is also important because she can often times feel a lot of mental pressure to cum, especially in the earlier stages of our relationship. For example, she will worry about me not being into it or feel pressure for not having an orgasm fast enough. Those kind of issues have gone away through with her becoming more comfortable with me.
Also you might have heard this before, but if you can orgasm through masturbating, you should maybe think about ways you can translate that into your sex life. For example, do you think about anything when masturbating? I know with my current fwb, she has a particular fantasy scenario that she always thinks about when rubbing one out. One time, I was able to make her orgasm through intercourse by telling her a story about this particular fantasy while fucking her at the same time. Problem is I have trouble staying hard while telling the stories so we haven't been able to have similar success outside of that one time. But the point is, if you can use whatever techniques, objects, fantasies, etc that work for you during masturbating and move that into your sex life, maybe you might have a little more success.
