This is a real delimma.
You can get rid of this hobby all together and stick to your girlfriend or wife. In other words, your life will get real limited this way. Think, you will be only making love to this one person for the rest of you life? Isn't that an ordeal, or boring in a way? (let's be honest with ourselves). Do you really want to miss out the rest of the forest for one tree? all the rest of fun, lovely, beautiful, sexy girls?
Then there comes all the STDs, HIV, AIDS... problems, dangers, deadly disease,.. stuff, that you have to deal with besides having loads of fun.
What a problem. Help me out here.
