PsychCentral reported that the desire for validation was one of the strongest motivators of human behavior. It's fine for you to want validation, sexual or otherwise. You might think that wanting to know if you sexually satisfy your partner makes you needy. But in real life, how can you tell if you're good in bed? If you and your partner were stranded on a desert island, how much time would you spend doing it? If you answered 24/7 that's one of the signs you sexually satisfy your partner, and your partner satisfies you.
