tips??

Me and my boyfriend have been together for 2 years and we have had sex countless times, each time is amazing and hot as all hell😍😍 I love him like crazy and he knows just how to turn me on, the only issue is that he hasn't made me cum once since we started having sex, now don't get me wrong I get a lot of pleasure out of having sex with him in giving him pleasure but it'd be nice to have an orgasm yah know? He never goes down on me either because he doesn't like the taste of when I'm wet but I'm very clean and I never smell, it's a vagina lol it's gunna have some taste am I right? But I've gone down on him plenty of times and swallowed, he just not comfortable going down on me and I completely respect it, can anyone give me some tips on how to have an orgasm easier or what he can do to make me cum without going down on me? how should I open up to him about this? is there something wrong with me lol. HELP!!
