Do all guys get super sensitive, after ejaculation ?

Yes, it is normal

Yes! After I ***, if my BF keeps sucking, stroking, or if I stay in him until I’m too soft to penetrate, it almost hurts…but it is a pleasurable “pain.” No harm is done to the glands—they just become very very sensitive!

Yes it becomes more senitive, but I usually keep going. Afterall I want her to climax 2X before I pull out. 

During this time, the penis might be touchy and further sexual incitement may really be agonizing, which is the reason men shouldn't continue attempting to have penetrative sex after climax, as they could cause themselves injury.

Sometimes I do and sometimes I do not get super sensitive when I ejaculate into my girlfriend. Sometimes I will keep on going because it feels so good, and I make her c*m again. 

I only had sex twice in my life and the second time (as well as my last time) when I had sex with my former girlfriend.  I ejaculated in her she wanted to play with it and start sucking on it, and when she did so, it started to feel real strange, and it also started to tickle. 

I assumed that was true for all men.  It seemed to be true among the men I talked to when I was in late teens.  (we talk to friends about everything in middle and late teens).   I stop pumping for a couple of minutes and just "lay" in till I'm ready for some friction.  If I'm gettin' sucked, I need a couple of minutes of VERY gently tongue. 

To be honest after ejaculation we don't really care.

Men feel tired and sleepy after ejact.....    Most men cannot have a ***** after s3x.  If your BF still wants s3x after ejact, it means he is very very horny and in a really good shape!

I don't know that I would call it supersensitive or what, but it can definitely become unpleasant.  Kind of like an itch that you scratch too much.  Goes from feeling good to feeling painful, maybe is the word?  Doesn't always happen but it definitely can.
