The skin around my testicles.. inbetween my thigh is very sticky, also after a workout it tends to sweat in that region alot, even after a shower.

Sounds normal: This sounds entirely normal. Some people sweat more than others, and this can show up mostly in areas where skin is against skin, e.g. in the genital and anal area, underarms, or under the breasts or other skin folds, especially in overweight persons. Use talcum powder or cornstarch to help keep the area dry and odor free, and wash and dry the area once or twice a day. Then no worries.

May be: Normal. Trial of powder may reduce the sweat and the stickiness . Do not wear tight or nylon underwears

Groin skin: Consider a trial of an over the counter anti-fungal spray or Gold Bond powder. Please do not remain in damp work out clothing but change and shower after workouts. If not helpful, please see a dermatologist. Peace and good health.
