Practicing qigong to nourish qi is very friendly and does not need to be completely feminine. As long as there is no sense of qi at the beginning of practice, you can abstain from sex properly. When you feel angry, you can adjust it through practice.
On the issue of complete abstinence, for example, if you want to improve your kung fu, you must completely abstain from desire at this stage of practicing Dan Dao until Yang's first move. But general qigong does not require this.
