HELPP

Hey yall!!So I’ve been dating this guy for five months and the sex is good but it’s not great. He cums quick and I always never get to finish. He also doesn’t go down on me but he expects me to go down on him(which is okay because I like giving head). I really like this guy but I honestly feel like when it comes to sex he forgets my needs. What’s some alternatives to get me in the mood? And How do I tell him without sounding rude? Below is a picture of how I started the conversation off
