Guy I’m dating lives alone but has 3 toothbrushes.. is this suspicious?

I’ve been there 3 times now. We’ve had sex. I haven’t ever slept over but he asked me to once. He says he lives alone and appears to live alone. There isn’t any indication of anyone else living there especially not a female... yet when I went to his bathroom I noticed he had 3 toothbrushes, all regular non-electric. Is this suspicious? Or do people normally keep many toothbrushes?
