Good day to you,
Unfortunately, to answer you it depends on what you like, what is your budget and ... well, knowing more about what you're looking for.
Assuming you have a vagina and it would be your first sextoy, you may want to use something that can stimulate your G point... But I can only assume.
So what would you like ?
Do you want a sextoy to stimulate your nipple ? Your backdoor ? Your vagina ?
If it's the vagina, would it be more to stimulate the clitoris or the G Point ?
Do you want to have the possibility to have it remotely controlled ? From an app maybe or synchronized with a video ?
