help?

my partner (17 trans male) and me (16 nonbinary) have been together for 5 months now. thing is, i’ve really wanted to yk have phone sex with him? im just to shy to ask, i always get shy with things.. plus i don’t know what to do. cause the only thing i can do to really get me to have an actual orgasm is humping like a blanket, stuffed animal, pillow etc. i trust my boyfriend with all my heart but i’m not humping a blanket in front of him, i use my vibrator sometimes but the vibrations are very.. strong. so, i don’t know how to ask? (context, me and him live far, i live in america and he lives in scotland.)
