Question

I suffer from premature ejaculation. We are both 56; relations take place once a month, or once every month and a half, and that’s legitimate, but because of all the excitement I “finish” before I’ve even started. As soon as I touch / caress / kiss her, it happens. I ask her to climax, but she isn’t willing, and rightly so, and I understand. Both of us, and especially I, are frustrated. So I thought of getting around the problem in the following way: to release semen two hours before relations with my wife, and then when we are together I’ll be less excited and I’ll have time to satisfy her until she asks me to come to her and finish inside the vagina….. Is that problematic?
Thank you very much.
