I'm not really concerned the question always just pops in my head and I asked basically the same question not too long ago I'm just young and I honestly don't understand some things and I'm very very paranoid!! But I was straddling my boyfriend and we were making out well for a while we were just talking and I was sitting on his thighs but one time I was sitting on his penis and yes we had clothes on. Is there any risk for pregnancy at all?? I was on my period 2 weeks ago monday so I have a while until the next on but it just worries me all the time!
