how to initiate in a romantic way

Im 21 my gf is 20, Ive been dating this girl for a year and we have a rlly good connection, we have helped each other throughout all the hardships we faced ever since we met and overall we have a rlly great relationship, However after 5 months or so of dating we had a talk about intimacy and affection, she said she isnt the most affectionate person which i did realise from the fact that ever since we met we have only had sex twice and both times were not sober, she is a victim of sa and i understand how that can make a person feel about intimacy and toching and im very supportive of the matter and never push her or even initate touch as she requested, the only times we cuddle or hug or kiss is when she initiates first. I would like to belive that im the best boyfriend i ever been to anyone in my life so far, i shower this girl with gentleness, flowers to the point where she dosent have space to hang them on her wall anymore, love letters, even tutoring her and helping her in her studies which i dont have much of a clue on but i research and try to help her as much as i can, her parents love me and even gave me the nickname "flower boy" and last month i even got her a promise ring and the next big thing is going to be a motorcyle which she has dreamed of ever since she was little. However latley i cant seem to shake off the lack of intimacy in the relationship, i talked to her about this already but she just started apologising and i felt rlly bad for her so we talked it out and came to the conclusion that we should take things rlly slow and she needs more time to think about it becuase she understands how much affection means to me. I dont know how to feel about my self, i feel like im a bad person for even wanting to do lustfull things with this girl that i love with all my heart and soul and she is stunningly beautiful just like her soul and im not sure what to do,. i want to learn more about how to initiating intimacy as a man in a romantic way for when the time comes and she feels more open about it if it happens. i would love to hear any suggestions thanks in advance
