Need Sex Advice

So I’ve been dating this guy for a month and a half now and he is the sweetest. From the day we met to now I can say that he is genuine and cares about me, although we don’t know each other very long it just feels different with him and I love that. To cut a long story short I want to have sex with him, but I haven’t been with anyone for about 3 years so I’m a bit rusty and I want to be good in bed and feel confident. Any advice?
