i think i need something bigger

so last week, i got my helix syn. ive only used it about 3 times and it just doesnt hit my prostate the way i want it to. i want a decent amount of pressure simply having it in, and doing the pc exerises increase the pleaseure. the helix syn only barely touches and there really isnt any pressure. i know that i still need to practice with the exercises and with the toy itself, but its simply too hard to relax fully. even though im pretty young, i feel like im just too emotionally unstable to really let myself go and relax all the way. before i got the aneros i used a 6in makeshift toy and it hit my spot way better. but because of its shape and being plastic, it would start to hurt. once i start getting the pleasure going, im able to relax a lot more. i can only do about 2-3hr sessions so its been a struggle so far. do you think an upgrade would be good and if so, what are some good toys including and excluding the aneros lines for a resonable price(around $40-$70).

what position is best ?

tonight is night 2 of using my helix syn that just came in the mail. it only feels like its barely scratching the sweet spot compared to my makeshift toy i used to use. im going to get some work done with it inside for about an hour and then ill really focus on the pc squeezes. what position maximizes how deep it goes and pleasure for you guys ?
