Go with silicone, I really like KY True feel and it comes in small packaging good for air travel. Wet Platinum is probably the slipperiest but it is super thin and messy. If you get too much on your hands it is hard to grab on when you need to ! I have used Astroglide also. I bought it because it seemed to be a little thicker then Wet Platinum and I did not think it would be that good based on how it felt going on but it was good once we started. Don't get anything desensitizing, you need to know what is going on back there lest you may end up with some damage.
I've been using Astroglide but now may look into coconut oil. During our threesomes my wife will work my hole with her fingers and lube before guiding his cock into my ass. It helps to stretch and work it a bit before he penetrates me...Once he's in and slowly fucking me she'll apply a bit more to his shaft when pulling back so it really slides in and out easier with more pleasure for both he and I.
coconut oil is great lube so long as you are not using latex condoms...... it can dissolve them, although having said that I used it with condoms many times in India without problems before I knew that! Recently I bought a load of Mates lube sachets and a recent top partner reckoned it was really good and didn't dry up .......it was a long 40 minute fuck session. Simon
