odd way to masturbate...

hello, i've been masturbating like this since i was a little kid. i do the thing where i put my hand between my thighs and squeeze real hard against my vulva. these last few years ive tried to stay away from doing that for various reasons (worried about the bones in my hand, masturbating in front of a partner, actually being able to get off during sex, etc). its usually a matter of i gotta cum quick. when i have down time i practice masturbation without using all that pressure. my clit doesn't really react like a clit should i guess, i find my lips to be more sensitive tbh, i love having my vulva and vagina rubbed like a massage. it hurts when someone rubs my clit too long. anyway, my question is - has anyone else done this? what alternative worked just as well for you? how long did it take to get out of this habit? thank you in advance xx
