Hi there, thanks for your question.

It sounds as though you are at a stage where you want to experiment with sexual things, which is pretty natural.

Your friend sounds as though he is very supportive in helping you to explore yourself sexually and this could be a good thing. If you have known him for some time and have a lot of trust and respect for him, then it may be fine to explore sexual feelings, thoughts and behaviours with him. It would be better to do it with someone you know and trust, rather than a stranger who you may not feel comfortable with at all.

While it is good that you have a friend willing to do this for you, there are a few things you may like to consider. He says he is happy to "teach" you. Sexual activities can't really taught because everyone is different in terms of what they like and what they don't, so there is no real right or wrong way. Teaching also sounds dominating, like he will be in control all the time and he will say what to do and not do. Sexual activity between a couple is usually about exploring and learning together, which may not happen when you do it with a friend teaching you.

Obviously you would become very intimate with your friend if you did these things together, and maybe one or both of you would start to feel things for the other person that you don't currently. You may need to prepare for this and be really clear with each other beforehand about what this experience is about, what is okay, what is not okay and what may happen if you start to feel as though you like him or he likes you as more than just a friend.

If you start to explore these sexual things together, you may get carried away and feel like you want to do more, like "full sex". Talk about this with your friend and decide together whether this is something you want to do and whether it would be okay or not.

All the best.
