I couldn't finger myself?

Instead of fingering first you should learn the art of masturbating.It is self stimulation for sexual satisfaction without intercourse. You will get fully aroused and also wet over there so thereafter if you push your finger in it will not hurt you. The vagina is so stretchable and flexible that it can accommodate any size of penis and after a mild pain initially there will be no pain but pleasure only if your life partner knows the art of foreplay and love making.
