How to make out with a guy is a common concern- and, especially if you feel inexperienced, having that passionate first kiss can sometimes seem like a daunting experience. Perhaps this is the sort of conversation that you could have with the guy involved, but keep in mind that all guys will want things to be done differently and if they are listened to, one will give information that will suit them but may not suit others.
The main thing to aim for is to feel relaxed, if you feel tense- chances are this will reflect in your kissing. Just start gradually, mouths should be open, and the tongues put together. Move it round in little circles and see what happens. Once this has been done try to assess what he is doing and if it is different to what was expected try to do the same as him. Don’t get too hung up on it and it will be fine.
There is not really a right and wrong way but what is best for both people. common advice is that it will just come naturally and you will know what to do at the time and this is right. As long as the person tries to relax and doesn’t spend all the time thinking if it is being done right or not.
One tip would be to keep a check on the saliva. If there seems to be too much back off a bit and wait until both mouths dry up a bit. The couple can end up with chapped chins and that is not a good look for anyone. Also remember to breathe - he may be put off if a partner keeps on passing out on him.
