Be thankful you're not in to stimulants, I returned from a parlour unsuccessful in my quest for a second jizz, needed up me at home laying on the stairs having a four hour wank and still no luck. My cock was swollen and purple and the additional weight meant if I pulled my foreskin back the added weight just shut it up again.
Thankfully a week and it calmed down, still a sympathetic sloppy bj might help, I'm not offering by the way!
