What's this red lump?

I have deveolped this large red lump on the inside of the top of my leg. Does anyone know what it could be? I have been with my hubby for 8 years and been faithful, so not 100% sure if is anything sexually related. Any ideas? It's litereally come up in the past month. 

Best to see your doc , would not think items anything to worry about ,how near to the vagina is it ?

No close at all really. It's on the inside of my leg at the very top. Does it look like the start of a genital wart? If so, I am a bit concerned about how I have got it as I havent had any sexual contact with anyone else in 8 years apart from my husband. 

My last post is being moderated-don't know why. Suggest you tap in dermnet and then Dermatofibroma. And I agree with Charles.

Not sure why a comment is bring moderated as I am a newbiee lol. Though I had a look at the notes and it said it can be moderated if there is a link in the reply. I have just had a look at Dermatofibroma and it looks silimar. would people agree that it doesnt look like a genital wart? as hubby would have some answering to do maybe? 

Actually I am not sure now about the Dermatofibroma as i am sure i am this but on my arm from an insect bite. It become a small hard cyst that I had removed but the thing on my leg is soft and no hard lump?

100% sure this is not a genital wart. Hubby in the clear!

That is good. When I started googling (worst thing I could have done) the pictures said it could be that so pleased it's not. 

Ingrown hair. Cyst. Keratosis. Go ask a dr before your hubby finds out you were doubting him. Worth the money.

It's free in the UK to see the GP and specialist if needed, except if you're in a hurry! If it's soft not likely to be Dermatofibroma. Is is sore/painful and how many mm across?

Go to dr and have it checked out don't assume it serious til dr see it
