Energetically is the key here, not physically - it is not the expelled fluid that results in the loss of Ojas, but the act of ejaculation itself - it all happens in the brain. This is kind of like drinking one’s urine. There are those that advocate that too - there is probably “some” use in such practices but cummon guys, there are enough well-designed supplements today to get replenish the nutrients, consuming body fluids is not the way to go. Traditionally, the Daoists and Yogis either resist from ejaculation using mudras like Vajroli etc., or are able to energetically draw back the lifeforce post ejaculation (could be one’s own essence, or a harmonious exchange of partner’s lifeforce which is what sexual alchemy is all about)…
