Is this a serious question? Well if it is the reason why he's "ripping" your clothes off is to get you naked as quickly as possible. Assuming he's in the same age range as you (18-24) he sounds like a typical horny guy.
if you want him to stop ripping your clothes off then I suggest you rip of his clothes first and then b4 he rips yours off tell him ur gonna strip for him and then you can take them off as slowly as you want
hes just excited to see you naked. I personally find it kind of hot when my boyfriend does this. I understand that sometimes you want him to admire what you're wearing, especially if you're wearing matching lacy thong and bra or something, but he's just excited. its nothing bad :)
