The question it pretty clear, if I allow dofollow outgoing links from any page, do I loose some of the page rank of that page? If not, why do people not have more 'dofollow' links?
I think that it's bad when it's too many external links from the web page/site, but your page will not lose any PR
If you add alot of outbound links , sute your page will be affected negatively , and it will loose some of its PR juice .
I heard, that page loses PR gained from internal linking, when it has too many external links. Though I never noticed that effect on practice.
First of all to answer your question yes you will leak some link juice. If you have a PR4 for example the and let's use numbers for example.. Let's say this gives you a score of 100 and you have 2 outgoing links.. You will split your page rank between the 2 pages so they each get 50 points.. Does this mean you end up with zero? NO. but it will cost you slightly for each link. Matt Cutts explains this well and this video should help out many of you with a better understanding of pagerank.. The video is long as is a great video to watch however if you just want to see the pagerank explanation it is about 6 minutes into the video..

Never about the juice! Just think about whether it will add value to your readers to have that link there. Think for the users, not just for search engines
Like others said, I think you're fine as long as you don't add too many outbound links - the page would look spammy to google.
ONE QUESTION: Does PR flow only to outbound links or it also flows through Inbound links? for example, on typical single post page, there are many links going back to homepage, other posts, sidebar links etc.......? How does it flow through all these links?
If you link out to external sites on the index page, but you have lots of internal pages to pass juice to, you will pass less juice to your internal pages. That's if most of your links are to your index page. Building links to internal pages will counteract this effect.
Thanks for sharing. So do you mean that if 100 people along with their backlinks comment on my page (say PR4), I may lose the PR?
As far as my knowledge is concerned the only thing that a website can get a link juice to your blog is through link exchange. One factor that people don't use do follow attribute is to prevent spammers that are spamming on comments. It's so hard to delete so many spam comments. Spammers spam on comments on do follow blogs just to gain backlinks and not the blog's link juice.
