Thanks for the responce girls! Makes sense and I need to accept and appreciate what efforts she does make. Enjoy and until next time!
The next one is not always stronger and better. If she says she's sensitive, she probably is. Some women are so sensitive they can orgasm right off, and that is all they want.
Well, you can't really guarantee that "... the next one will be stronger and better..." than the first. But, that's beside the point. She can't handle more than the one orgasm due to her hypersensitivity; and, that probably won't change. To avoid further frustration for both of you, it might be best to enjoy and accept what is; rather than attempting to "convince" her into doing what is clearly not be possible.
If she's sensitive it probably hurts. Don't push her into it.
