Orgasming while having sex

Whenever I have sex with my man (just recently lost my virginity) I be on the verge of orgasming but I never actually orgasm and it makes me upset because I don’t know how to 🤦🏽‍♀️ I can make myself but he can’t make me.. I feel like maybe I’m scared to orgasm so I hold it in or something.. any tips or advice on how to just let go ?
