Need advice and accountability

Hey guys! So I need some help. For some backround info I have a boyfriend he is amazing.hes 18 years old, Best man I’ve ever met in whole heart truth. Strong Christian, smart, caring, respectful, responsible, dedicated, and charming I love him to bits and pieces. He’s never had a girlfriend before not because he didnt want one before but because he wasn’t focusing on that and he knew his goal was to marry the woman he dated. Which has been a strong conversation lately and we are looking to get married in the next couple of years. We have set strong boundaries for ourselves. We will not kiss until we are married and are waiting to have sex until marriage. (Nothings wrong with kissing it just makes it special and helps with desires) which is my issue I’m facing. We are both struggling with wanting to at least kiss. But I am struggling with sexual thoughts often, especially since I’m been going through lots of hormonal stuff. I have had sex before but he has not. I know that’s not the focus it just feels so good and I strongly want to show him affection in that way. I guess I’d just like some advice to get my perspective back on track :) thanks guys
