Spark trouble

Me and my boyfriend have been together 5 months now, and we're both inlove with eachother deeply but lately for the past couple days we seem to not have that passion in our relationship anymore and it can't be cuz 'not enough sex' cuz we have sex everyday, it also can't be 'communicate more' we talk so much together about everything. But idk if this is true but since I've been with him we never go out never go on walks. After school I always go over his house and then his friend Matt picks us up and we go on a drive. Could it be that we need to go out places more ?!! Like idk.
