two seperate phases

my boyfriend and i have known each other for about 7 years now and have dated for 1 1/2 years. hes gotten to the point in our relationship where he doesnt want sex as much and is more comfortable watching tv and cuddling. i know this happens in a lot of relationships eventually, but im just not there yet? im still in a place where i want lots of sex, so this is really stressing me out. i dont want to pressure him at all and im just really unsure of what to do right now.
