My boyfriend and porn

So me and my boyfriend are 15 and we have been together for about 8 months and its going great however he always watches porn even when im there. I have no problem with that as hes a teen thats full of hormones so Idc however when he finds out I have masterbated he get angry at me and says that it wrong for me to do it as its a guys thing. I know we wont break ip over this but I dont know what to say anymore mostly as when he does it he always want to hold me close as he does his thing even tho I dont touch him there.

Please help coz I dont know what to say anymore
