If you’re wearing shorts or working out, inner thigh protection is a little harder than putting on protective clothing. I see this type of chub rub as a triage system.
First, try using something you already have at home:
Lotion/Oil – Your favorite body lotion or favorite oil (coconut is a hit) can create enough of a barrier to reduce friction between your thighs (or other body parts). This method may not last very long if the lotion or oil absorbs quickly.
Powder – Baby powder or cornstarch can stop your skin from rubbing. This method can be messy, so you can use a washcloth or powder puff to apply.
Deodorant– Your deodorant can also work to ease the friction. Just apply the same way you normally do.
Silicone Lubricant – sounds silly, but the same silicone lubricant you may* keep bedside will reduce friction and is long-lasting.
If any of those don’t work, time to bring out the big guns.
Powder– There are powders designed exclusively to prevent chafing, the most well-known being Anti-Monkey Butt Powder.
Bar– These look like deodorant, but serve the express purpose of reducing friction. BodyGlide is a prime example that I have used.
Secret Shield is a smaller brand that I have heard recommended more than once. It is available on etsy.
Cream – Monistat Anti-chafing gel comes in a small tube. It goes on clear and provides a slight barrier between the legs.
*(nay, probably should, but that’s another post)
