HELP!! Orgasms

Morgan
I just turned 18 and I was in a relationship with my boyfriend for a year. We were both our first but I dumped him because I caught him cheating on me with 17+ girls sexually or verbally but anyways the whole year we were together I didn't enjoy sex except once and I still wasn't close to having and orgasm, he orgasmed everytime. Is there something wrong with me? I were tampons and I didn't know if it messed me up done there(my vagina).
