I am 24 years old female, from past one or two months, I have been feeling a lil pain in my anus during potty irregularly. Yesterday my boyfriend tried to insert penis inside my anus, although he tried twice or thrice, only once it went inside, that too only the tip.It was almost in, and quickly he took it out. I felt a strong pain for some time. Next morning i did potty twice, I saw drops of blood in my potty both times and but I felt a little pain only one time. is it serious? should i see gynecologist?
