Is it normal to check out a female acquaintance of yours and jerk off to her Instagram pictures even though you are single?
No, it's not normal, dude. Stop doing that, real men don't jerk off to female friends pictures. Real men don't feel the need to jerk off at all. Real men know how to control their libido and not be slaves to sexual urges.
If you’re horny, not getting sex and the photos are arousing, I think it’s somewhat normal for a man to do that, no?
Most men have jerked off atleast once in their lives but jerking off to your female friend? I don't find that normal. Besides, you need to be able to control your sexual energy to be free from lust.
Ok, you’re saying a guy can be aroused, yes. But shouldn’t feel the need to masturbate? I’m a woman, so am only horny a few days out of the month. With men, I know it’s different because of the testosterone. I think I get what you’re saying, that it’s about self control. I thought men, biologically though, needed to release like twice a week? Maybe I’m wrong.
It's somewhat common, among men. I wouldn't call it normal behaviour. and I wouldn't call it socially acceptable either.
