Increasing blood flow to the penis? Help

Hi guys I just wanted some advice on something. I won't go over everything happened to me again but to cut a long story short after doing P.E. for a brief period of time my erections loss some strength especially with my "morning wood" which rarely feels all that hard upon waking up and it usually subsides pretty quickly. it lacks the "throb" from before, the glands don't engorge as well and blood can drain from the head fairly quickly when not masturbating. There was only one time last year I can recall where I woke up with a raging boner, I used to get them all the time and they would often last for 15-20 minutes but there so rare for me now. I can get erections most of the time and spontaneously but there not instant steel erections I used to have previously.

I honestly thought all these issues were in my head and stayed away from the P.E. community for over a year but I know it isn't the fact is my blood flow has weakened and my erections still don't feel as hard as they should be. I am 23 by the way so age really has nothing to do with this.

I know I should be glad I can still get a hard erection and I don't essentially need Viagra just to get my dick up but after all these years I still want to get my old strong penis back close to how it was.

Some suggestions would be appreciated on how I can increase blood flow to my dick (PC muscle exercises aside for the moment). I am trying to improve my diet and drink more water. I am not sure if this will truly make any long term difference but I have started using hot wraps throughout the day mainly once in the morning and at night before bed. I have noticed that my penis when flacid feels slightly heavier after doing them and just touching my dick can cause an erection. I often find though just doing the hot wraps triggers a semi hard on.

I know you guys are probably thinking I have no problem because I can get an erection without that much problems. However it's the strength and hardness of my erection that is the issue and has been for years now.

I am thinking about maybe using some sort of herbal Viagra for a few weeks or months just to see the results but I am not sure yet I don't have much knowledge about using it. What I do know is that it would boost blood flow.

Please answer if you can I would really like some advice on this. I am happy people here are gaining with P.E. but that didn't work out for me I would be a very happy man again if I can restore my penis back to it's full strength.

Thanks

Why don't you want to work your PC? That helps strengthen erections.
