Anxiety about sex, when to have sex? Please help!

[Incredivle]

I have anxiety about having Sex.

I want to avoid the times of having sex when I am worried.

But sometimes, I won't feel worried until I start having sex.

So, if I want to avoid the times I feel worried whilst having sex, but only feel worried when having sex, what do I do?

I only want to have Sex when not feeling worried but sometimes I won't start feeling worried until I start having sex

From what you said, I assume you're not a virgin.

There isn't really anything you can do to overcome this anxiety.
Once you become experienced, and you become used to having sex, then the anxiety should go away.

Also, if you're so worried about this anxiety, maybe just don't have sex?
Seriously bro, there's more important things in life than sex.
