I'm having a bit of an issue and really hope you can help me out. I've gotten into the habit of masturbating once a day, but when it comes to being with my girlfriend, I'm struggling to get a second erection quickly. It seems to take about 2 hours for me to be ready for round two. Is this something that might need medication, or are there exercises or other solutions I could try to improve this? Would love some advice on what to do.
