I do rowing exercise on a rowing machine about 2-3 times a week at quite high intensity, and whenever I exercise - about 80% of the times - I feel a tingling sensation in my higher inner thigh/genital area, which is quite uncomfortable. It kind of feels like a pre-orgasm sensation, but not in a pleasant way and it is embarrassing.
I just wanted to check that it may depend on maybe lack of oxygen during exercise or lack of blood in my legs, since rowing is quite a compression exercise, or whether it may be something more. This started only a few months ago when I took up the intensity of my training, and as I said it does not happen ALL the time I exercise, but it is worrying me a bit. When it does happen the sensation remains for a while at much lower intensity even when I lie in bed after the shower.
I would appreciate it if you could give me some advice on this.
