Dont stress just go and enjoy yourself,whilst i know this is frustrating remember there is more to a relationship than sex,just enjoy each others company too,it will happen honest.
While on that long weekend, relax and have a couple of drinks to ease the anxiety. If this continues, you might want to see a doctor.
Thanks cheshchesh819, we are going for a long weekend on Thu 28/10, it's a little bit frastrating as I really need to go but I am so stressed at the same time ...
You need to relax more stop focusing on it this with dampen your performance,stress can cause all this to happen just dont rush these things it will happen when you feel relaxed and stress free,try caressing each other more before actul sex,the more fondling the more excited you get,good luck.
