I 23f and my bf 28m have been together 4yrs and in the beginning sex was alright. Nothing to txt the group chat about but he got the job done if I was the one doing majority of initiating. Now that time has passed I quit being the one initiating or getting ontop because the pain was not worth the gain. He’d nut in less than 2 minutes and I’d be left high and wet. Fast forward to now our sex is non existent and I see from his Reddit search history he’s been having a blast watching porn but won’t give me a second glance. When I went to google something from his computer the genius left “is it normal to be lustful in a relationship” in his search. So he clearly isn’t going through a sex drive issue he’d rather cum in a towel to a stranger. How do I express to him that I NEED to be fked SOON and not that minute man shit but really railed like a grown women. I’m apprehensive to even ask because if he’s satisfied with his towel and Reddit porn what would incentivize him to fuck his boring ole bed warmer of a gf.  
I’m completely open to suggestions on how to approach the subject. (The porn isn’t my issue more so that it’s been three months and we’ve only done it once for less than 60 seconds.)

Advise on how I ask my bf to fk me like a grown women.
