He doesn't know where my vagina is???

Okay I'm still a virgin but I've fooled around with past boyfriends and have gotten pretty much the closest you can get to intercourse. Anyways, I'm ready to settle and have been dating this guy for almost 7 months. He's total hubby material;);) Anyways, he's a virgin too but I feel a lot more experienced than him. The farthest we usually go is like making out with a little boob-touching but mostly he just holds my waist or my thighs. Anyways, today he kind of leaned over me while making out and started to like grab the region below my bellow button. He gradually got lower until he was two inches above my vagina then started to kind of rub..... I think he thinks he was rubbing my vagina but lol it was kind of...off. He's so sweet and shy and tbh I was surprised he did it. Like I totally don't mind but I don't know how to address the situation. Do I leave it alone and let him figure it out on his own? Do I try to educate him or maybe was he like not going for my vagina??? Idk any advice is great I really just don't want to hurt his self-esteem
