Along with others, i'd stop shy at calling it "addiction to cum," though the feeling definitely resonates with me ;-). i think the feeling is real/valid, but i think the definition "addiction" is too absolute, maybe narrow?
The sex drive is well documented as natural, but then people with beliefs get onboard and want to regulate it, it seems, since the beginning of recorded history. Coming from a conservative religious background, i was conditioned from birth to think and feel about my attraction to guys as "sinful." As a kid, i went to the library and looked up homosexuality and medical books prior to 1973 labeled it a mental disorder, so: "sick and sinful." le i was still processing out of my religious conditioning, i went through "reparative therapy" and the term "addiction" was used liberally if you were gay. A lot of conservative religions still consider gay as "sick," and being gay is also often automatically associated with pedophilia. Gay attraction is commonly compared to alcohol addiction.
Religion is a huge part of US culture, so if you grew up in the US, you've been exposed to it's influence and a lot of the homophobia that goes with it can become internalized and fly under the radar.
i look at our sex drive as similar to hunger, we get hungry, we eat to satisfy that hunger... that's an arguable comparison, and it can fall apart, but my intent is to put sex in neutral territory when it comes to the moral question of being gay.
Back to my feel that "addiction" is too absolute and narrow a term to describe the intense drive. There is some evidence of correlation (but not causation) between absorbed semen in women and reduced depression (excerpt and linked info below). i don't think it's a reach to assume a similar correlation with bottoms because the colon is highly absorptive too. But i know for me, my drive to receive a Man into me goes well beyond the "cum." In both my thoughts and feelings, i identify several distinct desires in me that correspond to what i identify as "Top." E.g., His desire to penetrate, open/mold ("fuck"), to possess, control, orgasm and breed. i see and experience all of those collectively from a Top, but the mix varies individually from Top to Top. For me, there's the physical fuck, but equally, if not more, the mind fuck (with all of the listed factors).
my crave and drive to be fucked always includes all of those desires, not 'just' the cum, and the degree of corresponding response of my desires (needs?) to be penetrated, opened, molded, fucked, possessed, controlled, receive His orgasm/pleasure inside of me, and cum... varies and is a reflection and connection that i experience with the individual Top.
"Several studies have investigated the potential link between semen exposure and mood. One widely cited study found a correlation between unprotected sex and reduced depressive symptoms in women. However, this study did not prove causation and other factors, such as relationship satisfaction and sexual intimacy, could have contributed to the observed effects.
Other studies have explored the effects of specific semen components, such as NGF, on brain function in animal models. These studies suggest that NGF may have antidepressant-like effects, but further research is needed to confirm these findings in humans."
