Why has using laxatives caused eretyle dysfunction

I have no previous medical history however do have a histroy of over mastebation.  This has caused a generally weakened condition of my sexual organ however it did not cause erectyle dysfunction or anything serious.

About 3 months ago I developed constipation. I took laxatives(glycerol suppositories) on three occasions and things were fine.  Recently I used these laxatives while lying down on my front.  I noticed that each time I used them my erection became extremely weak with weakened sensation.  I tried to masterbate and noticed the amount of my semen was reducing aswell.  I took the laxative again and it become even worser.   There is no doubt that by taking the glycerol suppositories it irritated/damaged my sexual function somehow, I have stopped taking them.

I am guessing the laxative damaged my prostate gland leading to these symptoms.  Although I have stopped taking laxatives passed 3 days my erection doesnt seem to be recovering.  

Do you have any idea what may  have happened?  
If the prostate was damaged through the rectum due to a harsh laxative will it repair itself or could the damage be permanant?

Thanks

Glycerine suppositories are quite mild and neither these nor any laxative of which I can think would affect you prostate. I cannot imagine how these could have influenced your erections or your ejaculate on a physical/chemical basis. Consider what other medications you have taken around the time of these changes in your sexual function. The level of your sexual excitement will have some effect on the firmness of your erections as well as on the volume of your ejaculate. If you are masturbating more frequently, the volume of your ejaculate and the firmness of your erections will be affected. You should consider evaluation by a urologist  and if all of this work-up fails to discover a cause, you need to consider an emotional evaluation also.
Best of luck!
