I'm terrified of sex

[Notonetodance]

Every part of it but mostly the thought of catching something.
I am so terrified it makes me cry. I came out of a LTR about a year ago in brick we both got,tested beforehand and remained faithful.

I'm scared that I'll catch something awful, that no one will then want me ever again, that because I'm so,scared I'm really crap at it. I don't enjoy it in the moment for fear of worrying about it all.

I feel so sad.

How will I ever move on and have any future relationships feeling like this?

I think you should consider some therapy OP, sex can be wonderful, one of the best things in life and there is absolutely no reason why you shouldn't get to feel that way about it. Or you might decide that it's not for you and life will still be wonderful. But carrying around these fears and being so upset is far from wonderful and no need for you to suffer any more. First stop, GP to talk things through and discuss your anxiety. You have started the ball rolling with this post and you should be proud of yourself for doing so and build on it with further action.

You're not terrified of sex, you have been having sex. You're terrified of catching an STI.
You need to realise that STI's can be transmitted through non protective sex. No-one should have non protective sex until both are tested and they are committed to a LTR.
Therapy for this fear should be addressed.
You also say you are crap at sex. An experienced lover would educate you and show you how not to be crap at it.
Both of your fears can be overcome.

How was the sex before in the LTR?
