Like you said the best sex will be when the male is bulking and not dieting hard!
depends. my diet is always super clean and at 600mgs test per week my sex drive is insane at 7-8bf%. I dont know how it would be at like 5% though, never been that low.
personally when I am bulking, im not as confident because I feel like I look fat so I am less willing to go all out. lol
