Me and my boyfriend have been together for a year and he used to finish very fast when we had sex. The first time was fast but I assumed it was since it had been a while for him, after that we had a tough time for about a month where he kept going soft and couldn’t stay hard. We realised it was because of how much porn he was watching and it made me really uncomfortable so he stopped. Since then we’ve had a great 10 months, and on average has been 20-30 mins each time which was perfect for us. However the last month or two has been really difficult for me, despite the sex still being good for me, I feel like it isn’t for him. It has been an average of an hour each time until he can finish, and it always seems like a big effort for him. I’m worried he either doesn’t find me attractive anymore or he’s starting watching too much porn again, any advice ?
