My boyfriend and I have only been having intercourse for about a month now but we've hit a bit of a bump in the road. We are very open about our ideas and love the idea of trying new positions... at least in theory. Whenever we switch positions it may take a few seconds to get everything right yet in that time he starts to lose the strength of his erection. I don't know if he feels that he's not pleasing me by taking a minute between position or what. I am enjoying every moment that I am with him and couldn't care less how long we take. Currently I'll take a minute and stroke him or go down on him until his erection is harder but I really think this is a mental issue. How do I approach this? I know that this is probably a sensitive subject and I don't want to make him feel embarassed or make it into a bigger deal then it is. Should I wait longer and see if the issue resolves on it's own?
