I am fine while having sex most of the time but sometimes I start thinking about not performing well or going limp and I go limp and its extremely hard to get back up because I'm so down on myself.. What can I do to prevent that..

This is normal, most men have an occiassional issue, esp when they start doubting.

Go get a checkup. They have pills for that.

Work on yourself confidence.

Stop getting distracted by your performance. Concentrate on her.

I'll agree... take care of the "YOU" issues first. Make sure you have had a recent complete physical exam and don't have any new untreated medical conditions in play. Its not normal to be going soft mid-session unless you are stopping to take a rest.

Read erotica novels they teach different things most people have no idea exist that and have pride if you got a its in your dna how to use it oh and porn my husband has learned tons by us watching hot flicks together we have a "movie" night once a week and god is he ah-mazing.

Did you notice this thread is three years dead and being that was the ONLY post they ever made here, they will never see that answer?
