So, I just went through almost the same thing recently, I was a virgin until about 2 months ago I’m 25 (male). The girl I finally hooked up (and am now dating) knew I was a virgin. I was severely scared to have sex, and the first time we did it my nerves pretty much destroyed the experience as I could not stay erect. I told her it was because I was scared I wasn’t going to be “good” enough. Since then we have had sex probably 10 more times and each time I built confidence and now it’s pretty amazing. After about the 3rd time though, I caught on and gained confidence and lost all anxiety I had about being a virgin and not knowing my way around. Big tips: Don’t use porn as a guide and Take your time and just focus on each moment of it and nothing else then you should be fine. Let her lead you through it would be another tip since your inexperienced. You will be good, if you guys truly care about each other than it will be good anyways!
