First Time

Hey Glow. So I've been preparing my body to conceive and carry a baby (taking prenatals, eating well, stopped birth control, etc). However, I am still a virgin (in my mid 20s) and my SO and I are going to start doing the baby dance this month. I'm super excited but also really anxious. I trust my SO and am eager to have a child together but despite my age sex terrifies me on some level. Does anyone have any suggestions on helping with anxiety or making this an enjoyable experience for both of us? My SO knows, said he would go slow, and is planning something special.
