Premature ejaculation and E.D

I am very helpless guy and suffering too much depression in my life. I am originated from Bangladesh but presently residence at France. I am 33 years old and I got married at 2009.
When I got married then I had just premature ejaculation (P.E). I could not control my semen more than 2 seconds. Within 2 seconds my semens came out. I was very afraid and discussed with several doctors. I tried several medicine i.e. desire-s, Cialis (10mg) Viagra, sildenafil, priligy and so on. But I did not see any good results after taking those medicines).
Present situation
Now I have the serious following problems:
- Erectile dysfunctions (ED). My penis has very poor blood circulation. I could not make fore play during my sex. My penis stand up only for 1-2 mints that is not enough for make out during sex. Within 1-2 mints my penis becomes again soft like before. If my penis is not so hard then how I will make sex. After that my penish never stand up. My penish size is only about 4.5 inch

- If I did not do any make out and start sex then I release my semen within 2 seconds. Maximum 2-3 strokes I can give during sex.

- Without make out it is useless sex. Then premature ejaculation is also here.

- If I do sex first time for 2 seconds then for the second time it will take about 7-8 hours

- The semen is very dilute like water

- I got married 4 years still I don’t have any children

- Recently I test my testosterone level. The report shows that I have bit low testosterone level. Now I am taking some testosterone injections

- I started now homeopathy treatment. I have taken lycopedium and calamedium for 20 days but not improvement.

- My life is very hopeless and feeling depression. Our family life is also going to finnish.

- I have some cold and allergy problem. If I eat some allergy food for example shrimp then start allergy in eye and flow.

Please help me to solve this propblem. I am requested to all experienced docotrs.
