i’ve been sexually actively for about 4 years and i’m about to turn 20. sex with my boyfriend is amazing and it’s feels so good and i’m definitely turned on but i never seem to be able to finish. i bought myself a vibrator a while ago and use it and i feel like i get super super close (my hands get all tingly which happens to me after sex, and i’m literally unable to control my body’s response to the vibrator) but i’m so close for so long that it’s just annoying. any tips?
