Remove specific excerpt

Hi,

I want to remove 2 excerpts from my blog and I´m not sure how to do it.

I don´t want a static front page, I want to keep it as it is now, but I don´t want these 2 specific excerpts to show, because apparently googleads are being blocked because of them. Still, I don´t want to delete them and want people to be able to find them if they surf through the right category (“Tantra”) but I don´t want them on the main page, were you get the exerpts of all the posts in the blog.

I have actually had this problem before so I changed some of the words that appear in the first lines (the ones that go to the excerpt) and it worked, but again my ads are being blocked since some days ago.

My website: http://www.practicaryoga.com
Posts that are causing the problem:
http://www.practicaryoga.com/sexualidad-sagrada/
http://www.practicaryoga.com/tantra-elevandose-al-espiritu-a-traves-de-la-materia/

Is there a way to do this? Hope to get some help!

Thanks.
