Is it normal that i feel post doing sex, i feel a lot of heat in thing

Well guys,

I am 22m, Had sex 4 1st time :).. I got a little crazy about doing it and did the in and out thing quite close to about five minutes and when my thing was out [ yup ve watched lot of movies where guys do it for hours together] .. I felt losing a lot of heat there and it was like if this is gonna happen then i dont want to have sex at all. Also at times when her hands were hitting my thing i could feel a lot of pain.. Is it normal or should i seek some sort of sexologist or some thing. ya it made me feel like i passed out in between half way and didnt give her any satisfaction. what if I end up doing the same thing when i get married ..

Just wanted to know if is it normal or some thing.. and how do you guys overcome it.. may be applying oil or some thing over it...or taking some sort of medication related to it.. wel if my question is not appropriate sorry guys for wasting ur time and it cant be removed. jst felt needed a little help cos in a country like mine I couldnt ask others for such favors as they would laugh at me..
