i guess its different for everyone, i remember when the first guy in our crew got some and we asked him how it was he said "felt like ****ing a cloud. a warm cloud." he just confused me with that, ive never ****ed a cloud and has no way to connect with that haha
But Charlesedwin was asking how it felt
physically after having sex, not during intercourse.
I would classify what your friend said as an aftermath
emotional feeling, because really, there is no physical changes that happen after sex for the first time (unless you got some STD

)
EDIT: "Physical feeling" was the exact term Charlesedwin used... hmm, I assume you mean emotional feeling.. of course there is a change in emotions after you have bang for the first time. You feel triumph because you feel more like a man.
