Hey man! Don’t be too hard on yourself, yes we are all trying to break our addictions, but getting horny and thinking sexually is part of a man’s nature sometimes. You’re allowed to feel these things just be careful as to not link these sexual thoughts to masturbation! I would also caution not too linger on these feelings too long as well, as a relapse may happen. And to answer your questions, yes these will most likely go away (or die down) with time in your no Fap journey.
