How to get my man penis to work

I have been with my boyfriend going on 3 years and I’m starting to get sexually frustrates. When we first got intimate he lasted one round. Mind you I have never been with someone for just one round, so I was completely shocked. After time the intimacy continued to be one single round. I guess I’m just sexually frustrated because I have such a high sex drive and want it all the time. Now we barely have sex and it usually once a week or every 2 weeks. I have previously discussed with him if we can have more spicy time but it rarely happens. I’m just so so so sexually frustrated and need advice. I also forgot to mention that every time we have sex it’s the same thing. I have asked him to try toys (I have a full drawer of them) and he never uses them. It’s almost like he’s so inexperienced. I also have some kinks and every time I mention it he never does anything. Please give me advice.
