Don’t fake it.
Believe it or not, most women do NOT climax during intercourse. This is nothing to be ashamed of, and you definitely shouldn’t lie to your partner about whether you did or not. In fact, a lot of women physically can’t orgasm during sex. Your partner will eventually find out that you’ve been putting on a performance between the sheets and it will bring your trust into question. Instead, show them how you reach your climax. Make him feel involved by telling him what to do with his hands (or mouth).
