Hello, Thank yo for writing to HCM, If we are talking about anal sex than definitely there should be some kind of pain should be there and even bleeding might be there if having rough sex. As Anal sex must give some pain because of size of anal is too small and for entering penis in it pre cum amount should be good because without that it cant enter easily. as i had gone through your query i would suggest that it might be possibility of internal injury while having anal sex that could be the reason for some kind of sensation to you. In your query it should be the same issue and for solving the problem of pre cum i suggest that go for foreplay and Oral sex first before you go for intercourse because it will help for pre cum and also you and your partner will have more pleasure than normal Anal sex. Also you should have to use lubricant because no pre cum will be there in anal. You may try different positions which could gives you less pain and more sexual pleasure. Still if you find any query you may have to concern a good doctor they may suggest you better. Hope you will find it helpful. Thanks & Regards, Dr. Gaurav Prajapati
