My Bf Makes Me Really Nervous!

I rlly love my bf. I just find that I get rlly nervous about him. Like if he tells me he’s coming over I’ll get SOO nervous. My hands get clammy & I get butterflies in my stomach. It doesn’t last for that long... after he’s over & we’re hanging & talking I feel more relaxed. How do I stop myself from getting so nervous? Does anyone else experience this?
