How do I tell my bf I don't want sex?

Josie

I'm in a long distance relationship. I haven't seen my boyfriend in over a month, but I will on Tuesday. What is the best way for me to tell him I don't want to have sex wth him over this trip? I've felt disconnect from him during long distance and I'm old fashioned. I don't know how to describe this in a way he'll understand.

I'm nervous he'll think something is wrong in our relationship when in reality I just need to warm up a bit. Any advice? (We normally sleep together)
