19M exploring my body

Hi I’m 19M and have recently opened myself up to exploring my body I would say I am a straighter individual but would be interested in having fun with a trans female or guy if the situation was correct. I haven’t really explored ass play much but in what I have done I’ve rlly enjoyed it does anyone have any advice on what sort of dildo or toy it may be worth buying happy to have comments but dms are always open 😀
