How should i act around my bf?

I'm 14 and he's 13.... we both go to Robert townson highschool in Sydney Australia... I've liked him for a month and a half and we kinda talked for awhile before going out but we've been going out for 5 days.... at recess and lunch I talk to him but sometimes its awkward silence .... I've only hugged him when I leave to go to whatever subjects next after recess/lunch.... I really like him and I know he likes me too ..... I want to kiss him or.hold his hand or sumfn but I don't know how I'm supposed to approach him with that .... he's a lil unpredictable...(Btw remember I go to HIGHSCHOOL ....just coz I say words like recess doesn't mean I'm in primary school bahahaha I'm 14 almost 15 lol
