Question
I read your book about 3 years ago (Ultimate Premature Ejaculation Mastery) and had gotten to a place with a few partners where I could last as long as I wanted. About 18 months ago I started getting blood in the semen and it would backfill into my bladder. I have had this on and off. I have experimented with quick ejaculations not trying to delay with. I blood. And it seems when I flex my PC muscle (pubococcygeal or the pelvic floor) 3 or more times during sex or masturbation, I get blood in my urine and ejaculate. I went over this with my doctor and went and got scoped by a urologist. They found nothing as it healed up. Have you heard of this before? What would you recommend I do to delay ejaculation?

Answer
Wow Patrick that doesn’t sound too good. But the same happens to me sometimes. I have an enlarged but otherwise healthy prostate. The last time I had it ultra sounded the experienced doctor said that was common with an oversized gland. So I don’t worry about it since it’s only occasional and temporary.
If yours is normal sized I really don’t know what to tell you. I haven’t heard of this from PC clenches alone.
- Is the urologist you consulted experienced with similar conditions?
- What is the size of your prostate?
- Are you forcing Ejaculate into your bladder with intense contractions?
- What does that feel like inside?
Thanks again!

Somraj: Well there’s nothing really definitive about the whole subject. Scientific research is ongoing. Different women describe different kinds of orgasms different, like clitoral being sharp or superficial, and g-spot being deeper and spreading. But I’ve read the opposite as well. There are fewer commentaries on cervical ones but they tend to refer to uterine jostling which creates a deeper and more profound experience. Your question seems to be aimed towards the physical experience. In Tantric Sex we focus on and expand the sensations created by the flow and flood of sexual energy. Those perceptions are even more all over the map, which in my opinion is a good thing. More up to a lover’s preferences and creativity.
