extreme sensitivity in penis head

[afireinside]

Ok so ive always had a problem with premature ejaculation but lately for like the last week the head of my penis has been extremely sensitive and sometimes slightly sore and a little tingly in the head....Its to the point were I can just be standing/walking around doing something or put a little bit of pressure on the area and I start to feel what I guess you could call the very beginning sensation of an orgasm but not quite cuz I don't get off. Also normally I can have dry sex and never get off unless I have direct sexual contact, but the other night my girlfriend and I were making out with clothes on and she was on laying top of me and she started kissing my neck and ear and in like two minutes or less I got off with no movement down there whatsoever it was really embarrasing and frustrating.....It just gets very annoying because it happens all day and all night so I have barely even been getting any sleep and its hard for me to concentrate on doing anything because that feeling is always interrupting....So I was just wondering if anyone else has ever exerienced this bad of a sensitivity to contact or if anyone can help to let me know what the heck is goin on because I seriously think this is making me go crazy
