Looking for some advice here. This is going to be a bit personal so please go easy on me here. I'm 25, never been in a relationship, and still a virgin. After no interest from girls during my school years, my confidence was shot. I tried dating apps for 3 years until I finally got a girl to go out with me. My confidence was even worse at that point. After a few dates, she wanted to have sex, but I pretty much had an anxiety attack and couldn't go through with it. I've had a history of anxiety struggles which I told her about, but she wasn't very understanding and left. With no support system around me, my confidence hit rock bottom. I gave up on dating completely, and just tried to focus on me for awhile. I tried to narrow down what caused that attack, and settled on a combination of performance anxiety, fear of intimacy, trust problems, and all of the religious hellfire bullshit from my upbringing.
Fast forward through the worst year of my life, and I now have a new job where the girls here are all interested in me. I really don't know what changed. I'm still the same me, but I guess I'm just in an environment that suits me better. They all flirt with me, but one of them is trying really hard to get me to ask her out. I like her a lot, she's very beautiful, and would love to go out with her, but every time she tries I get those same fears creeping back in so I avoid the topic.
What should I do? Go out with her and try to push through those fears myself? Try to talk to her about it and hope she understands? Hold off until I feel more comfortable and ready for it?
Thank you in advance to anyone who takes the time to read and respond.
