Here is Perplexity's opinion. Hope it helps.
To lose an erection without ejaculation, you can try several methods:
1. **Meditation and Deep Breathing**: Focus on your breath, and try to clear your mind of arousing thoughts. This can help relax your body and reduce the erection[3][4].
2. **Distraction**: Think about something else, like a complex problem or a non-arousing topic. This can help shift your focus away from the erection[4][6].
3. **Cold Water**: If possible, take a cold shower or splash some cold water on your face and hands. Cold temperatures can decrease blood flow to the penis[6].
4. **Change Position**: Shift your position to reduce any stimulation that might be maintaining the erection[7].
5. **Wait It Out**: Sometimes, the erection will subside on its own with time[6].
