One of my Ex’s(F) used to love getting a creampie ..
So when we got together and the first time we fucked I pulled out and came all over her stomach. The next time we had sex, I was telling her I was about to finish and without saying a word she grabbed me by the waist and forced me deeper. I was very much into that and I continued until I had to cum, this was over 10 years ago and was also my fist time finishing inside someone. Needless to say I loved it and so did she, almost every time from that point I would finish inside her and if I didn’t she would make sure we fucked again that day or night until she got her pussy filled.
We would always have a huge mess to clean up after as she would lay there and let it spill out or she would get up and put her panties back on and let to leak into them.

There’s a tangential link between serotonin production and insemination. A case could be made that regular semen exposure is useful as an antidepressant.
