My boyfriend is not as interested as when we first started dating

Lately my boyfriend seems distant like he used to be so clingy and now it's like I hardly get hugs and kisses .... But we have sex ALOT ... Just no foreplay and he jumps right into it ... Which we all know is not as enjoyable ... Help ladies ??? We've been dating for almost two years now and it seems so routine !!!! I need opinions and things to change it up some before I go crazy !!!
