How do you spice things up?

My boyfriend and I have been together for 9 years. Almost 10. I LOVE sex. I’m into the freaky stuff lol He is a little more on the shyer side. I mean while we’re in the act he’s into it but foreplay seems to not be his thing! And I’m so over of getting straight to the point! I try kissing his neck while he’s playing his video games or something but he just laughs and I stop. Like i feel like he’s not attracted to me. I was considering getting some lingerie but I’m scared he’s gonna turn me down and I’ll just be so embarrassed.
