Is it normal to be so turned on by your s/o?

Its been like two years with my baby. We started out as just hooking up but casually going out on dates. Then we eventually began to be somewhat of an item and then became official. But throughout it all, I still get as turned on as the first day we hooked up. Is this normal? Is this a good thing? I am an affectionate person but he turns me on so much unlike anyone else. So its not like I get horny by just anyone. But with him all the time. The best part tho (which is prob ironic) is that he doesn't ALWAYS feel the need to have sex...like me lol. But I know he does get turned on by me, he just doesn't always want to do it and that makes me feel really good cause it just means he doesn't want to be with me only sexually. I love it when he plays with me, sometimes even publicly. Hes just silly like that and when he initiates the sex, I can't say no of course. If anything, I have to stop initiating the sex activities before he thinks I'm some kind of sex addict or thinks I just want to be with him for the sex. But this man makes me so happy emotionally and physically. I feel really good for the future because I know one of the problems with long-term relationships or marriages is the sex activity and one is not getting satisfied by it. Well I have a feeling that I am satisfied for life with him and because I give him sex or willing to be sexual with him and he enjoys it, he's also satisfied for life. Sometimes he tells me I'm too sexy so I try to be conservative for him but at least he knows that he'll never be bored sexually with me. So is this normal or even okay? Or I should be aware of turning him into only sexually attracted to me?
