To any virgins actually nervous about their first time or anything like that; I would say not to fret. It can't be overstated for the guys, porn is not real life. You're having sex with another person so you'll need to be in tune with her needs as well and not go at it like a rapist fresh out of prison. And never be nervous. There are married men in their 40s that still can't handle business in bed so their wives are... any think 20% experience 80% communication and willingness.
My 2 cents anyway
Edit: And sex will come. Just lay off the porn and let the thirst (your natural instincts which is how we all got here) consume you and guide your swag haha.
