I haven't any libido or erections from 5 months till now after i failed in my first sexual experience will i be ok will my libido and erections back?

You'll be OK.: Sorry you are taking this so hard. If libido and erections ok. Before attempted sexual experience, then all should be well. It's a mind game that many young men get trapped in. Anxiety and negative experience leads to more anxiety and neg experience. You need to stop beating yourself up asap. Since it's been 5 months, you could benefit from psychological help to reduce your anticipatory anxiety.
