@B03 - It depends as others have said whether you are looking for a G-Spot orgasm or clitoral orgasm during penetrative sex. It’s not really known whether everyone with a vulva can have a G-Spot orgasm, but I definitely agree with exploring during solo play first so you know where it is and what type of stimulation feels good. This will give you a better idea about the type of angles needed. For me, legs on shoulders, reverse cowgirl and doggy are all good ones for the G-spot. I find that wearing a butt plug during penetrative sex can also help this as it helps to angle if that makes sense
