orgasms

Hi I'm posting this anonymously because I find it really embarrassing. I'm 29 and I've NEVER had an orgasm during sex or foreplay with anyone but can achieve orgasm by myself. Has anyone else got this problem if so what have you done to try and change it. I've asked my husband if we can include sex toys etc but he doesn't really care as long as he cums he's fine and I just feel like I'm left hanging every time. It probably doesn't help that my husband only lasts 7 mins max and it's starting to really get me down. Please help
