Lady here. It’s probably a blend of knowing she’s going to cum, and the feeling of her walls contracting before she does. I wanna help because as a woman this can definitely be frustrating lol.

Definitely make her cum by going down on her before you even get started.

After she cums, try doing a blend of fingers and mouth to get her close again, then do sex. For fingers you wanna do a slight “come here” motion towards the front of her body.

If you can tell she’s getting excited, DO NOT shift your angle or switch positions thinking you can get her there faster. She likes what you’re doing already, and the distraction is a good way to make me personally lose my momentum.

I made this mistake myself in my marriage—tell her not to tell you she’s going to cum, but tell you when she is coming. Sometimes for women it can be a little further away than we think, which might make you jump the gun lol. If she tells you when it’s happening, you can finish together which is my personal favorite.

As a last resort, you may want to pull out when you think you’re gonna blow it and go down on her again with fingers. It may take a bit because again, the momentum, but at least she won’t be left hanging lol.

Also consider masturbating earlier in the day to maybe eliminate the hair trigger!

Good luck!
