Going in a date for 3 months and no sex

So, I’m really confused, I’m seeing this guy for 3 months now, he is super sweet and we really have good time together, he comes in my house and I go on his, I’m 30 yo and he is 50 yo, he said he is slow when it comes to sex, but I’m starting to go crazy to have sex with him but he doesn’t really try anything and I feel shy to try to make him want it… any idea why a guy wouldn’t try to have sex with someone that he seems to be falling in love with??
