Never tried roids - I know that keeps up the libido - , but it's still like 6 or 7 times per week after 5 & 1/2 years. Used to be more but now the wife has a career. In other words, she is outta college, so the job sometimes gets in the way. Weekends usually leave us pretty sore... hehe. I am also a runner & I know all the cardio keeps the blood flowing into "parts" so I don't think I'll ever try roids.
It's really all about intimacy and communication for us anyway. I think some people try to base a relationship on sex. Sex will be great as an afterthought to the more important things like openess, honesty, selflessness. Meet each others needs in every other area and mind blowing sex will most definitely follow. Just my 2 cents.
i've come to the conclusion that a woman's sex drive originates in the tip of her left ring finger. and when you put a ring on it then the flow is decreased by the constriction of the ring.
