Only man in town

I 60 live in a small declining town, its better days are behind it. The major employer closed years ago. Only 9 of the houses are occupied the rest are vacant, no local shops left open. Of the twenty other residents I'm the only male left, the others are women ranging in age from 56 to 81. I sell mushrooms, herbs and cabbages as my income source and make regular trips to the nearest city to sell my produce and buy supplies for everybody back in the town. I'm like a travelling supermarket using my vehicle to keep everybody supplied with their needs. Of the other locals there are 7 who like me to satisfy their sexual needs as well, used to be more but as they age, they stop wanting sex. But I'm getting older and 7 are about my limit now anyway, but it keeps me very satisfied sexually.
