In Islam, afaik, fantasising about sex is haram.
If supressed they usually end up in dreams.
In Islam one should either marry or fast. Besides intercourse, one may also need emotional stuff.
I suppress them, and I am fine. They do not spill off in the real world to me. I do admit I have sometimes uncontrollable "jits" but that is only when I am half conscious. Otherwise I am good at suppressing.
I disagree, the more you focus on it, the bigger it becomes. Seriously, society has made marrying an achievement.
One can just stop focusing on one's desire and stuff.
Islam discourages being celibate. On the other hand, it encourages marrying ASAP, and have ones desires released in a halal (permissible) way. AFAIK.
Allahu alam.
