Well first off welcome to the group and let me just say that if it's the first time trying something there's no wrong way to do things if you and your partner are 100% honest and have complete trust in every aspect when it comes to finding your sexual level. I for 1 am 41 and I thought I was a freak in my 20s but I have far surpassed my own level and still broadening my horizon. So try everything, you never know, you may not have any preferences because you love them all whichever they may be!! I hope this helps you in your journey
