I'm certainly not into sado-masochism and much prefer pleasure to pain. But in a similar way that Durex sell lube potions specifically to give a you a tingle, you might have the courage to see how much tingle you can take. The following is from personal experience and I'm aware people may have different experience. I was once intrigued to know how it might feel to deliberately sting the knob (glans) of my penis with a common nettle. I plucked new shoots from a plant and for safety washed them in water. I then carefully held the sprig in a tissue wad and lightly brushed the leaves across my glans. Initially it was hard to say if it had any effect and so I dabbed the sprig in a more determined attempt to sting myself. It felt surprisingly good and gave me an extremely firm erection. Subsequent masturbation resulted in an extremely fast and powerful orgasm. Move on a couple of years and my wife had been reading the Fifty Shades series of novels which talk of sado-masochism in a relationship (so she says) largely exacted on the female. We talked and I mentioned how I had subjected myself to this pain and it was rather nice and I suggested she might want to try it on me within normal lovemaking foreplay. So one evening I gathered some nettles as before and with my wife wearing a protective rubber glove she applied the nettles. The nettles had actually been picked about half an hour by the time the were applied and, unlike my penis, the nettles had gone a little limp. As a result the leaves needed to be flicked quite hard against my glans in order to do the trick so I guess a fresher nettle harvest might be preferable. Over the next minutes as we kissed and fondled I was able to experience the most intensely enjoyable sensation with my wife not touching my penis at all. It was as if I was literally aching to penetrate her and my penis throbbed very powerfully. I told her it was like DIY foreplay for me. After sometime spend arousing her with manual and oral sex I guided myself into a position to penetrate her but then encouraged her to use my very hard penis to rub her own labia and clitoris—effectively she was using my penis to masturbate herself. The intensity of the pleasure for me of this added stimulation to my over-sensitised penis was indescribable. Eventually knowing that I would not last long during actual intercourse I penetrated. The thing about sex for a man, and I think this must be universal, is that the sensation of pleasure largely masks any pain. Accordingly, intercourse was extremely pleasurable although there was more than a hint of very agreeable pain in the background. However, at orgasm which was rather too swift the pleasure/pain threshold shifted as orgasm took place which added wave of slightly greater pain making the orgasm absolutely intense and able to last, in my case, for nearly a minute. Oddly, the pain then made it easy to sustain another erection within a very short time and while a second coming was nothing like as good it was still a two for one offer not to be sniffed at. If you felt unable to ask your partner to participate you could easily self-nettle prior to going to bed and impress her with the size or your erection and your selfless attention to her pleasure as you secretly enjoy the most wonderful self-induced foreplay sensations.
