Can’t get turned on

Soooo I’ve had sex and everything but I can’t masturbate. I used to be able to get turned on really quickly when I was like fifteen (I’m seventeen now) but I can’t anymore. The only way I get turned on is by being with a guy . I just can’t get wet. Like I could be in the mood to masturbate but I can’t actually get wet .I’ve tried porn and reading and imagination but nothing works, maybe I’m not doing it right idk? I really don’t know lol but it’s so annoying because I don’t have a boyf right now and I can’t release like I do when I have one and I get really stressedddd. Anyone experienced anything like this or have tips? Help a girl out xoxo
