So I'm trying to explore my tastes and dislikes as far a sex goes so I can be comfortable with myself because the other day I was with my friend and she stuck a finger inside, it felt okay but wasn't amazing I keep trying to do it to myself but it's a no go. I feel ambarrassed when I do it to her she really likes it. What is wrong with me? Am I not doing it right? Isn't it supposed to feel really good?
