Hi, about a month ago just after my last period, my boyfriend and I were playing around. He ejaculated after giving himself a handjob and wiped his hand with a towel. We talked for about 10 minutes and he rinsed his hand with tap water and dried it with again with a towel just before he started fingering me, no penile-vaginal penetration happened before and after this situation though. It happened just right after my period so I'm guessing that was a safe time. Right now is my 33rd day and I was expecting my period 2 days ago but my period usually starts on the 27th - 35th day. Should I be worrying or am I just overthinking and the stress of waiting is just delaying my period? May I know the risks. Please enlighten me, thank you.
