The Male G-Spot

Ever considered that nature understands exponential growth and that it intended us to be bisexual, so that we wouldn't persistently seek sex with women which could lead to mass pregnancy and, in turn over-population?  Maybe this is why the male G-Spot is in the ass?  Note: nothing exists that isn't part of nature or God's plan. That would be sort of saying that nature/ God has made a mistake.
