For me it started since I can remember. Woman with thick long hair always fascinated me, especially when it was really dark long mane. My first sexual experience then totally triggered it. It was lady with waist length dark brown hair, and she gave me my first blowjob ever. I finished in her mouth and it was a bit too much for her to swallow. So one portion of cum came out of her mouth dripping down her hair. She noticed it but did not remove it, it was still in when we were later walking outside. This was the total overkill for me and since the. i always try to shoot a load on the ladies hair.
