Advice

So I’ve been dating this guy for a while now And he’s the love of my life like we are always together and we have already talked about us getting married just not yet but recently I found out that he has been lying to me for five months about being in school cause he doesn’t want to disappoint me and that he just needed to wait until next fall to have the money for college. All I ever asked from him was to be honest with me and then he finally told me because he felt like he was gonna get caught soon. We have recently gotten past it where I forgave him and we have been more open with our lives. However ever since I found out our sex life just isn’t as good anymore, we used to have amazing sex almost everyday sometimes multiple times a day but once I found out we have sex maybe 3-4 times a week and I never orgasm even when he tries everything to get me too and I just really miss having great sex because I do still love him so if anyone has any advice on how to get back to our old sex life it would be really helpful
