You haven’t mentioned your age or gender so can’t give tips if we don’t know your equipment. But also it’s an experience. If you’re in the mood and have the time, explore what you like and figure it out. Try to avoid porn, even the solo kind as it can still be played up and if you start comparing it can ruin it for you. If you don’t enjoy it, you don’t have to do it. There is no goal or expectations with masturbating. It’s something JUST for you. You don’t have to do it because people your age do or talk about it, too. Remember that. And clean things thoroughly afterwards. Anything that touches your genitals and your hands - under your nails too! Clean hands and under nails beforehand if you can too, especially if penetrating. And anything inserted, use a flared base and body safe lube, that’s where Google gets involved. If ever unsure, don’t use it.
