It's kind of an annoying topic... And I do it sooo infrequently. I don't find it trememdously appealing despite how good it may feel at the time, but I usually can't seem to go for more than a few weeks at most without doing it. The person I sometimes think about if and when I do do it, has personally asked me to think of him, as he does about me quite often. So I think I feel less guilt because even i get lustful per se, in addition to the feeling of innocent love I have for this person, I know he consents to my use of mental imagery, and I know I'm still being respectful to him. And I don't think of having any kind of sex with him either; even my "sexier" thoughts are fairly clean in perspective. It makes me feel better that there are people who do it every day full of lust and lewd fantasy lol, because I think well, I could be worse. Oh man, I hope no one reads this, it's so embarassing lol.
