yea some guys r like that.. maybe you should just reach for him and kiss him.. my bf just chillax after sex.. he just lye there.. and i makes da move.. i guess all guys r different.
my boyfriend is the most affectionate, cuddly guy before and during sex. right afterwards, he rolls around, faces his back to me and falls asleep! most guys are this way.
Some guys actually need come kind of encouragement that he did something right. The kissing after sex maybe gratifying to him in less words. Meaning he thinks with kisses that he did something good. Like a reward. I wouldn't stress about it. It's actually a really sweet thing for him to do and maybe he's trying to let you know in his own way how special you are to him. If you aren't comfortable with it change it up and see how he reacts.
My guy likes to kiss and cuddle after sex. Only for a few minutes though because we are both so hot and sweaty we have to move away from each other to cool down.
