I have had two turp procedures and now have retrograde ejaculation. When my penis is erect, not one single drop will come out of it, no matter how strong an orgasm.
Takes some of the fulfillment out of the orgasm not to squirt out semen, but there are some advantages, in intercourse, oral sex and masturbation.
I am an expert on that last one, since I travel a lot in work and 'jack off' many many times out of town.
Back when I had the messiness of semen squirting out, I often jacked off naked in bed after work and then, with the semen all over my belly, would go in and shower. Now, I shower first and then jack off at my leisure with my cock staying dry and clean.
Now not having to clean up after the orgasm, I found that it was a great pleasure to keep on stroking after orgasm and let the skin of my cock roll over the now very sensative head. This gave me several more minutes of great pleasure.
Then, one day, I found my cock staying hard for a long time and then going into another orgasm. It was great! I then remembered that I was often able to get two orgasms on one erection when I was very young and having dry orgasms.
Now I enjoy a second orgasm a little better than one out of ten times. I am never sure when it will happen, but it is a great possibility to anticipate and makes me almost not care that I don't squirt out semen any more.
