I can’t cum!

My boyfriend and I will be celebrating our one year anniversary soon. We are so in love and have a great relationship. The only problem is that as long as we have been sexually active, I haven’t been able to cum for him.

It’s so frustrating. I don’t have a problem by myself, but in the moment I just can’t get there. We try different positions that help me get close, but then it never ends in fireworks (at least for me. He has had many happy endings!)

Help! What can we do?
