How to relax

Shantel
Hi. I need your help on this. I love sex I mean I can go on and on but I have a huge problem. I can't relax to have a climax or squirt I don't know what is wrong with me. I am 26 and I am with a wonderful man who is 33. I is amazing at sex also. This is not the first time I have had this problem I just don't know how to relax. Even when he goes down there. ?
