The longest I have ever gone without masturbating was from late October to early January of this year so I'd say about two months and two weeks. I noticed that when my body was used to going longer without it, my body could handle going longer without it. Here are some of the things that have triggered a "need" for an orgasm for me:
2. Feelings of guilt or worthlessness.
3. Feelings of loneliness or isolation.
4. Feelings of failure or feelings of inadequacy.
5. Feeling unloved.
A lot of times what triggers my desire is not actually related to sex at all. It's not an issue of desiring sex. It's an issue of wanting a drug essentially, one that I'm used to and one that can give me a false sense of being loved.
Right now, not orgasming is extremely difficult and frustrating. My body is having a very hard time and I feel like I need to start over with aiming for a week, then two weeks, etc again. Haven't quite decided what to do yet though.
