Any opinions on this?
I found this site that claims that exercising the front thigh muscle increases blood flow to the penis by over to 21%.
I’ve been trainig my quads a little since I read this and have noticed harder and more easy-to-get-at-all-times erections…a sort of power-up effect.

Hope it’s of some use to you…
