Hi,
Welcome to HCM.
I have read your description and understand your concern.
The problem you are having with erection is mainly due to associated psychological factors than physical one.
Tiredness what you could be facing could be due to iron and protein deficiency.
Kindly do the following to overcome the problem.
1. Kindly practice '
pause and squeeze' technique, which over a period of time helps you to sustain erection for a longer duration.
2. Take Tablet.
Tadalafil 30 minutes before intercourse to get good erection.
3. You need to overcome fear or
anxiety by doing
meditation regularly to keep your mind calm.
4. Include in your diet - almonds, banana, pineapple, saffron, cardamom, figs, honey and pumpkin, which are known to increase the blood flow to the penis and help to initiate and sustain erection.
5. Consume iron rich foods like dark green leafy vegetables, jaggery and dates regularly. Also you can take
iron supplements in the form of capsules or syrups.
6. Take
protein supplements in the form of powder to be mixed and consumed with milk twice daily. Supplement protein in your diet by taking pulses and egg white.
Once you regain your confidence and overcome weakness, you should be able to gain good erection gradually and perform better. Later, you may decrease taking medications or take only when it is absolutely necessary.
Hope the information provided would be helpful.
All the best.
