Question about relationship deals with ?

my gf and i have bn going out for 7months and she told me she was willing to go to 3rd base. i never asked her, she said she would her self. she said she wud only do it because she really likes me (loves me) and it has NOTHING to do with peer pressure, or anything like tht. we're both 16 and i guess im fine with it (lol i am a 16 yr old male afterall) but i do not want to make ne decisions i wud regret. not to b y or nething, but i am not hormonally-driven and am more mature than many others boys my age. should i wait? what should i do?
