Me and my boyfriend were kissing intimately while at sea swimming (in sea water - salt water), facing each other with me having my hips and feet wrapped around his pelvic area towards his back to hold on tightly to him. Our bodies were thus touching intimately (including our genital organs) but we both had our swimsuits on all the time. I could feel he was sexually aroused just like I was, as his penis was hard and erect, but I m not sure if he had an ejaculation or not, or if there was any pre-ejaculation fluid as we were in the sea obviously. This was 17-18 days from the first day of my last period. It is now 30 days since the first day of my last period and my next period hasn t started. I am currently not on birth control pills (I used to be, for reasons other than pregnancy prevention, such as acne-related reasons, but stopped a few months back as per my gynecologist s advice) and we didn t use any condom since we didn t actually have any sexual intercourse. Is there a risk I might be pregnant from this encounter and if so, how high is this risk?
