I am a 42 year old male. Don t have any health issues. I take care of myself for the most part. I do have a a decent amount of stress. Is it normal for my testicles to be tight and pink? This is specially true after sex. They don t hurt, but I do have a tightness sensation in the whole area. Almost in my bowels. I am sexually active. I do use protection, but not at all times. I admit I have sex at least four times a week several times a day. When I do have sex it last usually last at minimum an hour, each time. It doesn t hurt when I urinate and there is no discharge. I don t feel any lumps in my testicales and they are free moving with no pain. Is this normal, STD, a hernia, stress, or something else. This has only been happening over the last three weeks.
