Problem with bleeding

I haven’t had sex in a year (for a whole bunch of different reasons but that’s not important) and didn’t use a dildo or anything for a really long time and I just recently got one and I bleed a little bit almost every time I use it. I miss how good sex used to feel but when I use the dildo it kind of hurts (and it’s not bigger than anything I’ve experienced before). I didn’t even bleed the first time I had sex, so I’m just confused. Is this because of how long it’s been? Or maybe I’m just not turned on enough when I masturbate? I think I’m almost ready to start having sex again, but I’m worried I’ll bleed. Thanks for any guidance!
