Hi kumar.avaneesh0 welcome to HCM,
You seem to suffer from erectile dysfunction(penis looseness) and Premature ejaculation
both of which seems to have its roots from your anxiety
. Both these disorders have many organic causes but the way you have described shows that you might be having stress
and performance anxiety which interrelates these two disorders.
First your stress and anxiety needs to be relieved for bringing back the erection and then sexual therapy for sustaining the erection and if these modalities fail you will be given drug treatment which has its own side effects and it should be decided on risk benefit ratio by a doctor.
Wishing your good health,
