Does anyone else struggle with this? Or have past experience?

99% of the time I have sex I'm erect; however when making plans to conceive I feel physically and mentally tense (like full body internal tremors, and constant mental focus on doing it and if I'll get it up for the need).

I managed to get it done 2 out of the 3 times, but it took a lot of work and semi-erect sex. The final time; I couldn't get it up at all.

I'm anxious about it because I am normally "good to go whenever I want" and when I actually have to use my goods for a reason; I can't. I just feel like I am letting her down and it hurts me. The disappointment makes it worse.

- I'm 32, I have OCD, and have one child already.

Cheers!!
