Yesterday got head from my gf. Hard the first time and came relatively quickly. Went for it again after a couple hours and was not super hard and took me a while to cum. I was pretty exhausted the second time so that may have been a contributor. I've MO a few times in the past month which I will not be doing anymore (hurts the reboot) but i just wanted to know if it's normal for the second attempt at a bj to be softer than the first (as a result of PIED of course). Thanks
