Ok, so fordyce spots feel like grains of sand under the skin, that’s how they feel to me, as I have a lot on the right hand side of the labia minora... if you gently pull the skin and look at them, I notice that with me, they are slightly yellowish in colour and are scattered like pebbles. If you would feel better having a medical professional have a look, then just nip in and ask to seek their advice, I’ve been back a forth plenty of times for advice!
Best regards!
