Uncontrollable Wet

Hey guys! So my boyfriend and I are in a long distance relationship so when I fly out to visit him it's always the first time I've seen him in a while. Due to the distance I usually stay for a few days with him (which is great) but here is the problem..I get soo wet around him. The slightest touch of him hugging me/kissing or whatever makes me wet. It's uncomfortable to be going out places with him and have to worry about it being noticeable through my outfit. & TBH it's just uncomfortable. Any suggestions on what to do? Is this normal?
