Sukha, Mark Twain is attributed with saying: "Giving up smoking is the easiest thing in the world. I know because I've done it thousands of times." Although I wish you all the best in your quest for betterment, I feel you will be reflecting back on this quotation many times, simply replacing "smoking" with "sex." The longest journey starts with the first step, but seven steps (days) isn't much ... but good luck.
As for consequences, I see few, unless you start "bragging" about it. Then you will be questioned, cajoled, taunted and ridiculed. Some may also praise and support you. If you just work on your goal without sharing it with others, the only ones who will know are those with whom familiarity leads to the potential for sexual interaction. That will be a TRUE challenge for you.
