My girl and I are both 21, the problem for us is that she is very sensitive down below, so she doesn’t last very long before she has an orgasm. Nine times out of 10 it’s before me. After she’s come she doesn’t want to carry on, so I have to stop. She then either leaves me without an orgasm or give me oral sex to finish me off. But I really want to orgasm during sex more often! Are there any tips you give to fix this? It's really frustrating!
