weird feeling after sex

whenever my boyfriend and i have sex he hits exactly the right spot in most positions and it feels amazing but i also get sensitive after a while. when we are done i still feel the sensations for quite a while after, is that normal? i‘ve had sex with lots of men but this is the first time i feel this tingly and strange feeling in my belly for a long time after (it‘s not an orgasm tho). does anyone know what i mean?
