Sexual problems. Years as he is now 31?

My husband and I are married for 4 months, we couldn't have penetrative sex, he doesn't look interested.He wouldn't attempt itself until forced verbally many times, he wouldn't prefer visiting doctor for consultation. He says foreskin is long but doesn't go for the minor surgery, also doesn't attempt sex using precaution. He has this problem from the beginning, how he couldn't cure himself in all these years as he is now 31? He would lie and hide these issues, we were together for 1 year before getting married but he didn't tell a word about such issues. He would enjoy dirty talks, watching stuff but penetration is something he won't like. His lying and hiding issues are adding to this problem, it's making worse. He won't accept and acknowledge his issues, he isn't finding anything wrong in his actions.. after 4 months when things got worsened, he would say my reports are perfectly ok, that is what he said to ex wife also, but couldn't resolve his sexual issues. Can someone pls expln.
