I'm scared of hurting my boyfriend after he had a cyst removed from his testicles

My boyfriend and I have not had sex in a couple of weeks. He had to have a cyst removed on his testicles. I have been wanting to have sex with him for a while now, and it drives me crazy not to be able to make love to him. I'm scared to touch him and get close to him because I'm afraid that I will hurt him.
