Split Sets Of Pumping..

Do any of you guys do this routinely? I don’t always have time to, but I’ve noticed that when I do, after the second set my libido is crazy for hours after. Just thinking about sex and I start to chub up.. I do my main session before bed, because I have time, then if I wake and just do one 20-30 minute set I go about my day and feel like I just want and need to fuck!
