Honestly when Harry would come back from tour he wasn't the type of guy to want sex. He'd tackle you to the couch or mattress snuggling into the crook of your neck. His every breath tickling the bare skin that showed on your neck. He'd kiss your neck every once in a while and making small talk.
Honestly all he ever wants to do is cuddle after tour. He feels it like making up the time he missed from not being with you. He'd mumble I love you'a and I've missed you the boys are crazy all that stuff.
He'd just want to hold your small frame how he use too.
