Sex? Blowjob?

Hey so... I'm a virgin and I kinda wanna have sex with my boyfriend but like I don't know anything and I don't know what I should do. I am 15 and will be 16 in July. He is six days older and he isn't a virgin. He and I have talked about it an she said that it doesn't have to be right now just when I am ready. Also any info and blowjobs is welcome bc I have no clue what to do for any of this...... Plz help

Thank you☺
