Hemorrhoids :: No Bleeding But Pain On Touching

I'm quite young (23) and for a few years I've been experiencing hemorrhoids more and more frequently. I don't remember not having one in the last year : a new one always seems to replace another at a different place. For now the inconvenience is limited : there is no bleeding and I feel pain when I touch them, nevertheless my recent hemorrhoids are really between the interior and the exterior, which makes them shuttle a bit and create a smell sometimes, particularly noticeable after sweating. 

SOLVING ATTEMPTS AND DISCUSSION

To keep it short, I've decided to greatly diminish my straining and my wiping for the last three months, which were both out of the norm in my opinion. Surprisingly, it was quite the opposite of an improvement, but I plan to keep those habits and to add more vegetables to my diet (which is fine on other regards). Besides, I'm a rarely constipated person and I believe my stool is a bit softer than average.

If I had to guess what are the causes of my problems, I'd say :

-the stress is causing me to contract (tighten)myself you know where all day long, or even the night.

-keeping the stool inside instead of pushing might not be a good idea and might cause more harm than good.

-inadequate (not in length or strength but in the manner) pushing. -too much leg-crossing or other bad positions.

-bowel movement at fix hour every day, instead of waiting for the opportunity (which I find to be quite hard).

Could anyone help me with this situation ? I'm afraid to endure a life of increasing pain. A doctor's advice would be appreciated. Thanks.
