I Have Problems With Maintaining My Erection. Even If I

Question: I have problems with maintaining my erection. Even if I get an erection when we start foreplay, by the time I remove my pants, i lose it and it is difficult to get erect again. Even if i get an erection and start intercourse, I can maintain it only as long as my partner's vagina is not very wet and is exerting pressure on my penis. When it becomes wet, i feel it is over-lubricated and I can't feel pressure on my penis, which keeps it erect. I feel i have lost erection although i may not have. And eventually I do lose erection. What can I do to maintain erection when there is so much of lubrication in my partner's vagina that I feel my penis is too small within it and I can't feel the pressure?

Please see my answers below

1.Do you have hypertension or any cardiac problem? No

2.Since how long you are feeling such problem? I have felt this from a young. Everything was fine and i used to get good erections on viewing porn until I was about 20. After this time I think I started becoming more concious about when the ereciton happens, etc. because the more I watched porn, it used to take me more time to get erection (As opposed to the first few times when I got an erection even before the "action" in the movie started. I got married when I was 32 and I did have good eerction the first few times, but when my wife turned down because I didn't have a condom, I started being more conscious. Even whe I bought the condom I wold lose the erection before I put it on. The marriage was not happy and was stressful, which ended in divorce. I again go married last year - it has been a year. some times I am three-four times after taking taldafil and then a few times even after I stopped. But I am always conscious about the erection. My wife keeps saynig don't worry about it, let it happen when it does etc But I have the worry of not being able to satisfy her or not gettin a proper erciton, etc. She has never complained and always said she is happy.

3.Are you going through any stressful events in recent days? No.

4.Do you have anxiety or depression problem in past? Yes, in teh past I have had anxiety about this and i think i still have. Depression was unrelated to this but there was a brief period.

5.Do you have habit of smoking? I used to but I quit 4 years ago.

6.Are you having any prostatic problem, cardiac problem, high cholesterol or spinal . Only high cholesterol. I am also taking anticoagulants because I have had DVT three times in my leg. The doctors said my blood has a tendency to clot so I should continue taking it . I have Acitrom 4 mg and 5 g on alternate days. Sorry i forgot to mention this. i also have varicose veins (in on leg now, and the other leg was treated with radio frequency in 2012)

Thank you, doctor.

Even when have erection, I feel it is not as strong and hard as it used to be earlier. Is there a way to improve this?

Also, is using numbing spray good to retain erection?
