Hard time cumming

I have always had a hard time cumming my entire sexual life. In my 20's a bf introduced me to little bullet vibrators and I have sworn by one ever since. I rarely have sex without one and NEVER cum without my lil bullet. Lately, after almost 10 years, my husband has voiced that he is feeling insecure about it, in his own defensive way. I hate that he has built up these feelings all this time. I also don't want to have to choose between enjoying sex and making him feel sexually competent. I don't know another woman with issues like mine. At this point in the game is their something I can do to get off "naturally" (without the bullet)?
