I masturbate twice a week and I ejaculate four to five times. Dies these affect my general health. I am 47 years not married. I always want to get ma?

It's good for you. This keeps you comfortable physically, helps keep your mind focused, and keeps you ready in case you meet the right person. You're not preoccupied with erotica. Don't enter into marriage just for the sexuality, but because you know you've found someone you can truly love for the decades to come. Here you must be your own gulde. Be wise and good luck.
