Sex..life

So I've been with my so for about 14 years we've always done the basic positions missionary side from behind Etc but I've been telling him lately that maybe it's time to try new things because I don't easily get an orgasm he always orgasms even though lately as we get older he lasts a little bit more longer I'm wondering ladies what have you done to do something different in the bedroom because I feel so fat trying to do these crazy positions and then we get hot and then I just give up and then we get mad and it's just a mess we are still very young we're not even in our 30s he's 29 I'm 28 so I'm just wondering if there is any books or anything you guys tried knew what was the best way etc... he is not into toys so toys are out of the question I just don't want to feel like a big well on top of him trying to do this crazy pretzel stuff LOL
