Sex, baby

My boyfriend and I's sex is super sensual and romantic but for some reason I still can't get off, or he gets off way before I'm even close. I've actually never orgasmed from our sex and weve been together 4 years. He took my virginity. He likes to play it safe, I feel like we're an elderly couple.. 😐 I wish he'd open up to different stuff, but I am terrible at expressing what I want..
