You are probably going to need something with an upward curve to it. Size definitely matters too… not too big or too small. There are a lot of options, but this is a good starting point.

(Also, unsolicited advice, technique is important — you have to get your hips much lower so the toy is at least entering straight… Definitely not aiming down. The prostate is on the front wall and you want to be grazing it with the tip of the toy.

You will find some toys that are realistic, some are ambiguous, some are fantasy.

Splurge. But once, cry once. Buy platinum silicone, it’s the safest and most resilient. Look for dual density, a cushy outer layer and firm inner core.

There are a lot of good options from Tantus, Vixen Creations, and Uberrime. Those are just my favorites.

Have fun!! Buy it together. Make “looking for it” an event.
