I'm 22 and married I love my wife like no other and I have never had this problem before and we have had sex a lot but after we got back together after a long disagreement we have had sex about 13 times not as often as before but only the past 3 times I have been going limp for no reason its embarrassing and pissing me off my mind is on her and only her like it always has been please need answers and need them asap I'm afraid I'm going to lose her

Let her see you are taking steps to deal with the problem as in schedule a doctor's appointment to find out if this is a medical situation.

If you lose her because you go limp some, she does not love you anyway and you are better off without her.

So you go to the doctor, it can be stress, worry, medication you are taking, high blood pressure, prostate issues are a common reason..
