Here are a few suggestions, feel free to add more.
Normal orgasm:
- Stroking (even while cumming) on a metronome, and its speed could depend of how many points we have.
- Stroke only the shaft, click a button when we cum and then be told to let go.
- Milking the monkey technique (see spoiler or here)
- Spoiler: show
- Stroking with only one or two fingers, can be combined with stroking only the sides of the cock.
- Stroking slowly even during the orgasm.
Note that both milking the monkey and stroking the shaft can end up being very enjoyable if not interrupted. It may lead to a kind of prostatic orgasm. They also have the advantage to make the stamina take much less hours or days to go back up.
