Never Orgasmed

So I've had sex with 7 different guys and even though few of them tried, none of them could get me to orgasm. It bothers me and then again it doesn't. If it takes them too long of trying I get bored and just want them to finish and stop bothering with trying to finish me. I've tried masturbation and it never works. I actually somehow turn myself off. I love the physical connection which is what helps keep me turned on but I was wondering if anyone else has had an issue with getting off. I understand it's difficult to get women off, however I would like to know if there's alternatives to trying to figure out what to do.
