BF not finishing 😬

So my bf and I have been dating for a little and we’ve had sex a handful of times (he was a virgin before me) but whenever we do he always takes super long to finish (like two hours). He said he takes like 10 minutes when he jacks off so I don’t get why he takes so long with me. We had sex 3 times this weekend for like an hort each time and he never finished. Any advice?
