Get drunk and try again. Alcohol lowers inhibitions, so if your head is the problem, have a few drinks then see if you relax more. If you know you can take 3 fingers drunk, it looks less scary to try it sober because you got there already. As long as you do it alone, nobody will be taking advantage of you and whatever happens is coming from your own head, even if it's something you would normally hold back on.
have you tried using a vibrator on your clit?, also try using an aloe vera lube, you could also try playing with yourself when you have a bath,
I think so, even when I really want to I'm still nervous. Yh well I wouldn't hide it from him. Hopefully he stays. I think it's less scary when you do it yourself because then your in control of how far you go and pressure etc. Since my last post I have somewhat made progress.
