I've experienced clitoral orgasms many times on my own.
Though, I've only gotten one orgasm during actual intercourse, and that was a few months since we'd started having sex. That was with my ex boyfriend.
Now with my current boyfriend...we've only had sex once, and nothing happened. Ha, he felt guilty about it xD I told him I don't orgasm easily and now he's determined to not only get me to orgasm, but to give me the best fcuking orgasm ever
