How much is too much?

Ok I met this girl she’s nine year younger then me I m 45 she’s great I’m not planing on marrying her or anything like that we dig each other and we get along just great she’s sexy fun she loves hockey and a bunch of shit I’m into she would love to move in with me but I like living alone with my two dogs and my cat Meeko we’re just having fun you know. However she wants to have sex every time she comes over and that’s almost every fuckin day she’s wearing me out I hate to say it. But what do I tell her? She’s not a nymphomaniac. Or anything like that. But what do you think every day too much I wish should I tell her I hate to lose her as a friend like I said earlier, she’s great.
