This is not a joke and is rather embarring. I can only have an through masturbation.?

Please give serious answers only please. I can only achieve by rubbing myself with my hands just above the oris (direct stimulation is too sensitive) or if I use a vibrator. But either way,it does take quite a long time and I have to go way harder and faster than a man would be able to do through ual . Does anyone have any suggestions that would help me to achieve an with my boyfriend? He wants to help me but he is extremely uncomfortable with the idea of using a toy on me and would really like to have it be HIM (ie. his fingers or his ) that does the trick. Any suggestions would be really appreciated, as long as they're not just to laugh or make fun of my situation. Thank you.
