ladies i need your help.

I'm feeling really dissatisfied with my sex life. I'm in a seriously committed relationship of a little over a year and i just never want to have sex anymore becsuse its such a job. I've never climaxed before in my LIFE- not by my own doing or by someone else's. it sucks because he thinks that he has made me climax and.. well, i faked it :(

i dont know how to tell him how im feeling without hurting his feelings because he's so extremely sensitive (and a bit immature) so if i try to talk to him about an issue concerning him he takes it to heart and thinks something is wrong with him.

i just feel so bad.. i think of all the things we do in bed together and it doesnt get me excited or aroused. Not to mention he's an extremely touchy person, so i get frustrated and overwhelmed when he constantly has his hands on me or is wanting sex. his love language is definitely physical ( mine is more quality time or acta of service). i just dont know how to tell him that he needs to back off a bit without him breaking down over it.
