Sex Dilemma

Okay so I've been with my boyf for almost 2 months and we had just over a month before he asked me out. I'm just a really horny person and I'd love to do stuff and I really wanna have sex but I have two little sisters so my house is always full and so is his 😔 he's alright with waiting but it's really fustrating me and I don't know what to do, help?
