Aleixs, he just want to build a legacy with you, it's all in good fun.
I'm kidding, yes, he is horny. Just remember, horny people have no rights. horny people are NOT protected under the constitution. If you are horny I WILL find you and then you will be sorry buster. Unfollow me right now if you are horny, have ever been horny, or ever will be horny. This is not a joke. Please leave.
Despite centuries of study by the most acclaimed minds in our field, we still have yet to discover any cure for horniness. The only way to stop your brother from growing hornier and hornier is swift euthanasia. I recommend suffocating him with a pillow the next time he sleeps. It's a better fate than the horrible life he will live as yet another victim of horny. Many suspect that the cause is a devious ruse by an old god, likely Zeus or Loki. When horny, they enter the mortal world, concealing their true form through illusory magicks. Get the sharpest scissors you can and prepare for castration, you had best hope the case isn't bad enough that it's started to become a full-on hydra as you have to chop all the penis heads off at the same time to slay that variation of horny. Try adorning yourself with symbols of other religions, like crucifixes, menorot or copies of battlefield earth. That should keep his powers at bay.
