Is there something wrong with me??

So me and my husband have been together for 4 years almost 5 now been married almost 3 months lately when we have sex I never orgasm and I know not many women do but I used to all the time before and during my pregnancy our baby is 2 months old now and when I get close to my peak he's done finished and goes to bed.... I'm afraid to tell him I never finish because I don't want to hurt his feelings. But when we are done I'm always wanting more and also I'm wanting to find new positions to do because we always do the same exact ones and we use lube and when we do it makes me feel like I'm super loose and I know women don't ever get technically loose. I just don't know what to do or how to help this. He's the only one I've ever had sex with we both lost our virginity to each other. No bashing or negative comments please
